Hi Mohamed,
If your timeStamps are longer than your other data, then there will be some empty region at the end. For example, if your timeStamps are from 9:30am to 4:30pm, but your data are only up to 3:45pm (that is, the timeStamps array are longer than the other data arrays), there will be some empty space at the end.
Hope this can help.

i suffering big problem in timestamps 
is this correct to draw ?
for (int i = 0; i < x; i++)
{
DateTime res;
DateTime.TryParse(ds.Tables["Chart"].Rows[i]["dt"].ToString(), out res);
timeStampsx.Add(res);
highDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["hi"]));
lowDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["lo"]));
openDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["op"]));
closeDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["cl"]));
volDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["vol"]));
}
timeStamps = timeStampsx.ToArray();
highData = highDatax.ToArray();
lowData = lowDatax.ToArray();
openData = openDatax.ToArray();
closeData = closeDatax.ToArray();
volData = volDatax.ToArray();
and why not drawing and make massege (not in time period ! ) |

Hi Mohamed,
If you are using the Interactive Financial Chart sample code, and you obtain the message "No data available for the specified time period", that means you do not have sufficient data that is within the time range from "startDate" to "endDate".
To troubleshoot the code, please check if your data that are within the time range "startDate" to "endDate" is more than the "extraPoints" your code used.
One method to diagnose the problem is to simply print the important part of your data out as the error message. For example, in the original code, the error message is:
viewer.Image = errMsg("No data available for the specified time period").makeWebImage(Chart.PNG);
You can change it to:
string msg = "";
if (timeStamps.Length == 0)
msg = "timeStamps array has zero length";
else
{
msg += "Start Date = " + startDate.ToString() + "\\n";
msg += "End Date = " + endDate.ToString() + "\\n";
msg += "timeStamps[0] = " + timeStamps[0].ToString() + "\\n";
msg += "timeStamps[timeStamps.Length - 1] = " + timeStamps[timeStamps.Length - 1].ToString() + "\\n";
msg += "timeStamps.Length = " + timeStamps.Length + "\\n";
msg += "extraPoints: " + extraPoints + "\\n";
msg += "No data available for the specified time period";
}
viewer.Image = errMsg(msg).makeWebImage(Chart.PNG);
Now you can see the startDate, endDate, the actual time range of your data, as well as the number of data points in your data and the extraPoints you are using. You can then check if you have sufficient data that is within the range from "startDate" to "endDate".
If the above still cannot solve the problem, please let me know what is the message displayed.

Hi Mohamed,
To combine the "Interactive Financial Chart" with the "Finance Chart with Track Line" sample code, you just need to copy the code that produces the track line from the "Finance Chart with Track Line" to the "Interactive Financial Chart".
In brief, for the server side code, you just need to output the Javascript chart model. For the browser side code, you just need to copy the Javascript code that draws the track line.
I have attached an example for your reference.
Hope this can help.

and how to make timestamps array longer than other ??
they in one for loop ??
like this
sql = "SELECT dbo.Price_Data.TK, dbo.Price_Data.NM, dbo.Prices.dt, dbo.Prices.OP,
dbo.Prices.CL, dbo.Prices.HI, dbo.Prices.LO, dbo.Prices.VOL,
dbo.Prices.PD_TK_ID FROM dbo.Price_Data INNER JOIN dbo.Prices
ON dbo.Price_Data.TK_ID = dbo.Prices.PD_TK_ID WHERE (dbo.Price_Data.TK = '" +
ticker + "') AND dt between '" + startDate.ToString("yyyy/MM/dd") + "' and '" +
endDate.ToString("yyyy/MM/dd") + "' ORDER BY dbo.Prices.dt ";
ds = Co.Select(sql, "Chart", 102);
int x = ds.Tables["Chart"].Rows.Count;
for (int i = 0; i < x; i++)
{
DateTime res;
DateTime.TryParse(ds.Tables["Chart"].Rows[i]["dt"].ToString(), out res);
timeStampsx.Add(res);
highDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["hi"]));
lowDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["lo"]));
openDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["op"]));
closeDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["cl"]));
volDatax.Add(Convert.ToDouble(ds.Tables["Chart"].Rows[i]["vol"]));
}
timeStamps = timeStampsx.ToArray();
highData = highDatax.ToArray();
lowData = lowDatax.ToArray();
openData = openDatax.ToArray();
closeData = closeDatax.ToArray();
volData = volDatax.ToArray(); |

Hi Mohamed,
To make timestamps array longer, just add more dates. For example:
//After obtaining the timeStampsx, add more dates
DateTime lastTime = timeStampsx[timeStampsx.Count - 1];
timeStampsx.Add(lastTime.AddDays(1));
timeStampsx.Add(lastTime.AddDays(2));
timeStampsx.Add(lastTime.AddDays(3));
timeStampsx.Add(lastTime.AddDays(4));
Hope this can help.

I want to make time fequency in chart
Daily , weekly , monthly , yearly .. regarded to my data
i want to make it in dropdown list like frame ? |

Hi Mohamed,
By "time frequency", I assume you are referring to the time for each trading session (that is, a weekly chart means each trading session or candlestick is one week).
In the original Interactive Financial Chart sample code, there are already subroutines to get weekly or monthly data. Basically, to draw a weekly chart, simply pass weekly data to ChartDirector. (Do you have a database for weekly data, monthly data and yearly data?) If you do not have weekly data, you may get the daily data, then call convertDailyToWeeklyData. See the comments in the getWeeklyData subroutine. The same applies for monthly data as well.
If you want to "make it in dropdown list like frame", please just make the drop down list using standard asp:DropDownList. You may refer to ASP.NET documentation on how to make the drop down list. After making the list, you may modify your code to get the data accroding to the drop down list.
Hope this can help.
