Hi KK,

There are two methods:

(A) You may put two XYCharts (and therefore two plot areas) in the web page, and allow them to zoom/scroll. See the following for an example:

http://www.chartdir.com/forum/download_thread.php?bn=chartdir_general&thread=1177009173#N1187895184

(B) You may combine two XYCharts (and therefore two plot areas) into a single chart using the MultiChart object, and put the MultiChart on the web page. When the user zooms on the chart, your code can update the MultiChart.

Hope this can help.

Regards
Peter Kwan

Hi KK,

I have written an example for you as attached, in which the two plot areas are within the same XYChart frame.

Hope this can help.

Hi Peter,

Thanks for providing very useful information.

In addition to the above request, i need your help to fix the following:

1) X-axis Title (Label) is getting invisible while doing ZoomIn or ZoomOut. I want to get the
    X-axis (Label) title visible throughout any updation on the chart.

2) on the Chart2 object i'm not able to get the ToolTip?

3) By default the loading of the chart x-axis should be fixed to last three days i.e, from last
    three days to the current day.

Please find the attached code. Kindly update the solution to the above and send me back.

Hope you'll send the solution. Thanks in advance.

Can you send me your e-mail-id and contact details.


With Regards,

KK

Hi KK,

1) X-axis Title (Label) is getting invisible while doing ZoomIn or ZoomOut. I want to get the X-axis (Label) title visible throughout any updation on the chart.

The spacing between your two charts is too small. When you zoom in, your code configures the x-axis labels to have two lines, and the x-axis title of the top chart is pushed down and is hidden behind the bottom chart. The x-axis title of the bottom chart is pushed down too, and overlaps with the bottom bar that shows the x-axis range.

To solve the problem, please leave more space under the x-axis of the two charts, so there are enough space to show the x-axis title.

2) on the Chart2 object i'm not able to get the ToolTip?

In my original code, I configure the page to show the tooltip of both charts (I used m.getHTMLImageMap). In your code, you change it to show only the tooltip of the first chart (your code uses c.getHTMLImageMap). If you want to show the tooltip of both charts, please change it back to using m.getHTMLImageMap.

3) By default the loading of the chart x-axis should be fixed to last three days i.e, from last three days to the current day.

In the original code, there is a comment that says:

    // The initial selected date range is last 1 year
    GregorianCalendar viewPortCalendar = (GregorianCalendar)endCalendar.clone();
    viewPortCalendar.add(Calendar.YEAR, -1);

If you want to change it to 3 days, please change the "viewPortCalendar.add(Calendar.YEAR, -1);" to "viewPortCalendar.add(Calendar.DAY_OF_YEAR, -3);"

My email address is pkwan@advsofteng.net.

Hope this can help.
