  How to add extended trendline in finacial chart?
Posted by poohwen on May-14-2019 16:20
I found that you give an example of trendline in financial chart.

If I want to draw an extended trendline when I click twice in a financial chart then
the trendline will automatically extend both side to infinite.

Would you give me an example?

Thanks.

Hi poohwen,

From your previous post, I think you already know how to obtain the x-index and y-value at the mouse position.

When the user clicks the mouse, your code should store the x-index and the y-value at the mouse. After clicking two times, your code will have 2 points. You can then add a trend line using a TrendLayer. There are some examples included in ChartDirector:

https://www.advsofteng.com/doc/cdnet.htm#trendline.htm

For the financial chart, it is like:

// data array for the trend line, initialize to Chart.NoValue
double[] trendLineData= new double[closeData.Length];
for (int i = 0; i < trendLineData.Length; ++i)
    trendLineData[i] = Chart.NoValue;

// put two points in the trendLine array
trendLineData[xIndex1] = yValue1;
trendLineData[xIndex2] = yValue2;

// put the trend line at the main price chart
myMainChart.addTrendLayer(trendLineData, 0x008000, "Trend Line");

Hope this can help.

Peter Kwan

Hi Peter,

in your post,
// put two points in the trendLine array
trendLineData[xIndex1] = yValue1;
trendLineData[xIndex2] = yValue2;

I want to know what is the yValue1?

I can get the mouse.y but don't know how to convert it to the yValue1.

Would you mind give me an example?

Thanks

Hi poohwen,

In my response to your previous enquiry a few months ago, I have provided an example to obtain the y-value given the y mouse coordinates. See:

https://www.chartdir.com/forum/download_thread.php?site=chartdir&bn=chartdir_support&thread=1547294028#N1547802174

The above example draws the y-axis data value at the mouse position. It includes code to obtain the y-axis data value from the mouse position, that's why it can draw cross-hair y value on the y-axis. It also includes the code to obtain the xIndex given the x mouse coordinate.

I forgot to mention that if your code is using a non-zero "extraPoints" parameter (called "extraDays" and set to 30 in the above example), you would need to add it to the xIndex to create the array:

trendLineData[xIndex1 + extraDays] = yValue1;
trendLineData[xIndex2 + extraDays] = yValue2;

Hope this can help.

Peter Kwan

Hi, peter

your code is work. Thank you for your kindly help.

But in your another example

https://www.chartdir.com/forum/download_thread.php?bn=chartdir_support&pattern=&thread=1405104488

If i want to directly draw a line instead of in the Paint event handler
but draw in the
        public void drawChart(WinChartViewer viewer).

How to draw a line directly in stead of using trendlayer.

The reason why i want to do that is I could store many trendlines(points in array)
and draw them directly in the mainChart.

Thanks.

Hi poohwen,

To draw the trend line in "drawChart", just all the code to draw the trend line in "drawChart". In the mouse event handler, you can obtain the coordinates, then call "winChartViewer.updateViewPort". This will trigger a ViewPortChanged event. In the ViewPortChanged event handler, it can call "drawChart". In "drawChart", it can check if there are data points selected by the user and draw the trend line accordingly.

If you have multiple trend lines, you can store the coordinates for the trend lines in a data structure (such as a List). Then in your drawChart routine, it can iterate the List or array to draw all the trend lines.

Hi, peter

i try to modify your suggestion in the
https://www.chartdir.com/forum/download_thread.php?bn=chartdir_support&pattern=&thread=1405104488

it work

the code like

            double[] trendLineData = new double[closeData.Length];
            for (int i = 0; i < trendLineData.Length; ++i)
                trendLineData[i] = Chart.NoValue;

            // put two points in the trendLine array
            trendLineData[80] = 150;
            trendLineData[50] = 100;

            // put the trend line at the main price chart
            m_mainChart.addTrendLayer(trendLineData, 0x008000, "Trend Line");

But in my application it fail to draw a trend line.

i try to use the code like
            curBar.trendLineData[9000] = 10500;
            curBar.trendLineData[9400] = 10650;
            // put the trend line at the main price chart
            m_mainChart.addTrendLayer((double[])Chart.arraySlice(curBar.trendLineData, startIndex, noOfPoints), 0x008000, "Trend Line");

I know the current total bars data is 9999.

So I fixed the x-index and the y-value.

But it did not draw a trendline.

Any problem?

Hi poohwen,

I am suspecting the problem is due to incorrect data.

For example, if your startIndex and noOfPoints are not within the range of your trendLineData, then the trend line will not appear, because your code uses arraySlice to cut the trend line data away. Or after slicing, there may still be trendLineData left, but it is less than the "extraDays" or "extraPoints" parameter in "FinanceChart.setData" so the line will not be displayed.

If you would like me to diagnose the problem further, is it possible to provide a more complete example using hard coded data. Everything (including the startIndex and noOfPoints and all the data) should be hard coded for testing. This provides a way to reproduce the problem.

As an example, the following is a fully hard coded charting code that works. Please try to modify it (eg. by adding the arraySlice line) until it does not show the trend line and then inform me what is the code.

public void drawChart(WinChartViewer viewer)
{
int noOfDays = 100;
int extraDays = 30;

RanTable rantable = new RanTable(9, 6, noOfDays + extraDays);
rantable.setDateCol(0, new DateTime(2002, 9, 4), 86400, true);
rantable.setHLOCCols(1, 100, -5, 5);
rantable.setCol(5, 50000000, 250000000);

double[] timeStamps = rantable.getCol(0);
double[] highData = rantable.getCol(1);
double[] lowData = rantable.getCol(2);
double[] openData = rantable.getCol(3);
double[] closeData = rantable.getCol(4);
double[] volData = rantable.getCol(5);

FinanceChart c = new FinanceChart(800);
c.setData(timeStamps, highData, lowData, openData, closeData, volData, extraDays);

XYChart m_mainChart = c.addMainChart(400);
c.addCandleStick(0x00ff00, 0xff0000);

double[] trendLineData = new double[closeData.Length];
for (int i = 0; i < trendLineData.Length; ++i)
trendLineData[i] = Chart.NoValue;

// put two points in the trendLine array
trendLineData[80] = 150;
trendLineData[50] = 100;

// put the trend line at the main price chart
m_mainChart.addTrendLayer(trendLineData, 0x008000, "Trend Line");

// Output the chart
viewer.Chart = c;
}

Hi Peter,

I modified the dragtodrawline example in the attached zip.

Please add CSVReader.cs StringConverter.cs Struct.cs into the project.

Extrack T1-*.zip and copy T1-*.txt into the executable directory.

You might see a FinanceDemo Chart using my data.

1.If you unchecked the checkbox "AddTrendLine"

the chart is what I want and I am using now.

But it will not show the trendline.

2.If you checked the checkbox "AddTrendLine"

the chart will show the correct trendline.

But it is not what I want to see.

3.I hardcode the trendline without using the mouse XYValues.
As you taught me that I can use the mouse XY to get the related xIndex and YValue.
In this demo, I just hardcode the value to simply the code.

Would you help me to find what's wrong in my program?

Thanks.

Hi poohwen0908,

I am unable to run your code, because I do not have CVSReader.cs StringConverter.cs and Struct.cs. Also, it seems the file T1-20190517.zip is incorrect. Internally it contains the same file as T1-20190515.zip.

Anyway, just by reading the code, in your code, you call the addTrendLine with hard coded data. Please change it so that it uses data obtained from the mouse.

In your code, you also draw another line in the mouse event handler using e.Graphics. Please do not draw in the mouse event handler if you are drawing in the drawChart method. Instead, just obtain the coordinates in the mouse event handler, so that the addTrendLine code in drawChart can draw the trend line. (A few months ago, you have enquire for the code to draw the crosshair cursor. You can find the code to obtain the coordinates there.)

Below is an example for your reference:

Thank you peter,

the reason why i hardcode the trendline array is that I already know the Y-VALUE after mouse click or mouse.

And the T1XXX even the same file does not matter with the result.

They just for test.

Please check my problem if you checked the "AddTrendLine" checkbox in the upperight corner.

  Re: How to add extended trendline in finacial chart?
Posted by Peter Kwan on May-21-2019 20:53
Hi poohwen,

In my testing, with the given data, I found that the error is caused by using the incorrect coordinates and data array for the trend layer.

(a) All the data arrays that passed to the FinanceChart must be consistent and of the same size. In your code, the data that is passed to the FinanceChart is viewPortTimeStamps, etc.. In my test case with the data files, the array length is 844. However, you use the curBar.trendLineData array, which is has 7000 elements. This is inconsistent and causes the problem.

(b) I found that the full length of your data (curBar.barPos) is 3370. However, you put the trend line at 3800 to 4000, which is beyond your data range. So even if you fix (a), you cannot see the trend line. The trend should use coordinates that is within your data range.


For my "drag to draw trend line" code, it works once the code uses the correct data array.



if (chkTrendLine.Checked)
{
    curBar.trendLineData[3000] = 10500;
    curBar.trendLineData[3200] = 10600;
    double[] viewPortTrendLineData = (double[])Chart.arraySlice(curBar.trendLineData, startIndex, noOfPoints);

     m_mainChart.addTrendLayer(viewPortTrendLineData, 0x008000, "Trend Line");
}
else
{
    curBar.trendLineData[3000] = Chart.NoValue;
    curBar.trendLineData[3200] = Chart.NoValue;

}

// put two points in the trendLine array
if ((y1 != Chart.NoValue) && (y2 != Chart.NoValue))
{
    double[] viewPortTrendLineData = (double[])Chart.arraySlice(curBar.trendLineData, startIndex, noOfPoints);
    viewPortTrendLineData[x1] = y1;
    viewPortTrendLineData[x2] = y2;

    m_mainChart.addTrendLayer(viewPortTrendLineData, 0x008000, "Trend Line");
}


Hope this can help.

Regards
Peter Kwan

Hi Peter,

Thank you for reminding me to use Chart.arraySlice.

                m_mainChart.addTrendLayer((double[])Chart.arraySlice(curBar.trendLineData, startIndex, noOfPoints), 0x008000, "Trend Line");

I forgot to add that in the addtrendlayer.

It work now.

But I found another problem.

The image shift slightly if I addTrendLine.

The highest price position without trendline(in T2.png) is lower if I addTrendLine(iin attached T1.png).

How to fix this problem?

Thanks

Hi, Peter,

I have one more question.

How to check if I click in the trendline?(not in the postion where I click the start or end position of the trendline)

Then I can move or delete the trendline if I have many trendline in the graph.

Thanks.

The maxmium value of your original data is around 10565. However, the trend line you added includes a value at 10600. So if the trend line is added, ChartDirector must extend the y-axis to fit the trend line.

In brief, if you do not want the axis to be changed, please use data values that are within the data range if your original data. If the code uses values outside the data range, ChartDirector will adjust the axis scale to include those values.

Hope this can help.

Regards
Peter Kwan

Hi poohwen,

You can create an image map for the trend line(s). This allows you to detect if the mouse is on top of the trend line by using hot spot events.

For example:

... create chart with trend line as usual ....

// Output the chart
viewer.Chart = m;

// Create the image map only after displaying the chart
if (null != myTrendLayer)
{
    StringBuilder imageMap = new StringBuilder();

    // xxx is an identifier to help you determine which trend line the mouse is on top
    imageMap.Append(myTrendLayer.getHTMLImageMap("clickable", "trendId=xxx", "", m_mainChart.getAbsOffsetX(), m_mainChart.getAbsOffsetY()));

    .... if you have multiple trend lines, please append their image map to together

    viewer.ImageMap = imageMap.ToString();
}


The trend line can then trigger hot spot events. For example, you can handle the MouseEnterHotSpot event to detect if the mouse enters into the region of the trend line:

private void winChartViewer1_MouseEnterHotSpot(object sender, WinHotSpotEventArgs e)
{
    if (e.AttrValues.ContainsKey("trendId"))
    {
         // The id of the trend line
         string id = e["trendId"].ToString();

         ......
    }
}

Similarly, you can use the MouseLeaveHotSpot to determine if the mouse leaves the trend line. There are also other hot spot mouse events, like MouseDownHotSpot, etc..

Hi Peter,

It's all my fault.

I should not use hardcode X, Y value.

I found that I can show the correct value in TrackFinance is that it get the value of xIndex in the layer of the chart(drawingArea) instead of the correct xIndex of my data array.

Then in my example I can't get the correct xIndex to show the correct TrendLine.

The main reason is that I set the viewer to part of the chart.
            viewer.setFullRange("x", curBar.barTime[0], curBar.barTime[curBar.barPos]);

            // Initialize the view port to show the latest 20% of the time range
            viewer.ViewPortWidth = 0.25;
            viewer.ViewPortLeft = 1 - viewer.ViewPortWidth;

            // Set the maximum zoom to 10 points
            viewer.ZoomInWidthLimit = 25.0 / curBar.barPos;

Can you help me to slove this problem?

Thanks.

Hi Peter,

In the mouseClick or mouseMovePlotArea,
                if (e.Button == MouseButtons.Left)
                {
                    MultiChart m = winChartViewer1.Chart as MultiChart;
                    if ((null == m) || (m.getChartCount() == 0))
                        return;

                    XYChart c = (XYChart)m.getChart(0);
                    //int xValue = (int)c.getNearestXValue(e.X);
                    int xValue = (int)c.getNearestXValue(viewer.PlotAreaMouseX);

No matter I use
c.getNearestXValue(e.X); or c.getNearestXValue(viewer.PlotAreaMouseX);

The xValue I get is not the correct one I need.
It return the xValue of the layer
like in the trackFinace
                for (int j = 0; j < c.getLayerCount(); ++j) {
                    Layer layer = c.getLayerByZ(j);
                    int xIndex = layer.getXIndexOf(xValue);
                    highValue = layer.getDataSet(0).getValue(xIndex);
****   this xIndex will show the correct high value in the legend,  but I need a absolute xIndex value of my dataset not the layer subdataset

Thank you for your kindly help!

Best Regards,

Hi poohwen,

From your previous code, the data you passed to FinanceChart is the "viewPortTimeStamps" and other viewPort* arrays. Your code create these arrays from your other "full data" arrays using arraySlice, which means your viewPort* arrays are offsetted from your other arrays by the startIndex.

When you pass the data to FinanceChart, you can ask it to remove the lead data using the "extraPoints" variable. In your earlier code, the "extraPoints" is set to 0. However, if you do not set the "extraPoints" to 0, you would need to add this back to the index too.

Have you added back the "startIndex" and the "extraPoints" to obtain the index to your original arrays?

Hi Peter,

You got it.

I did not add it even I copy slice of my array.

Thank you.

Hi Peter,

If I want to draw two diamonds in the the trendline(where I click the mouse in the chart to set the trendline), what should I do?

I can get the x, y now(thank for your help).

Can you give me an example?

Thanks.

Hi poohwen,

You can add a scatter layer using the same data arrays as the trend layer:

m_mainChart.addScatterLayer(null, viewPortTrendLineData, "", Chart.DiamondShape, 11, 0x0000ff);

Hope this can help.
