Hi,

I am trying to use TeeChart 7.0.0.6 to plot. If I try to plot only one series, the plot does not show up on the graph but I try more than one it shows up.

I verified by using TeeChart 6.0, this issue does not occur and the chart plots the first series without any problem.

I have gone through Microsoft Visual debugger and verified that the Chart object indeed contains the plot values of the of a single series.

In the ocding I am using:

Chart.Export.SaveToJPEGFile teeChartFileName, false, 0, 100, chartwidth, chartheight

The output jpg file does not contain the plot. It is the same when I export it using the the .tee option as follows:

Chart.Export.asNative.SaveToFile teeChartFileName, true

Can someone help me with this issue?

Regards,

Ravi

Hi Ravi,

which code are you using to generate the Chart and populate the Series ?
Would you be so kind to post the code with which we can reproduce the problem "as is" here ?

Hi,

Please find outline of the code which we are using for your reference:

------------------------------------------------------------------------

MySeriesNumber = 0
seriesTye = "scLine"

'objNodeList is an xml containing data point info

Num = objNodeList.length - 1

redim myXarray(Num)
redim myYarray(Num)

for each datapointnode in objNodeList
myXarray(t) = datapointnode.getAttribute("localeTime")
myYarray(t) = datapointnode.getAttribute("datapointValue")
next

execute "Chart.Series(MySeriesNumber).AddArray objNodeList.length, myYarray, myXarray"
execute "Chart.ChangeSeriesType " & MySeriesNumber & "," & seriesType

'2 more series are added after the first one
'code remains same

.........
........

'Series 0, 1, 2 are plotted above but only 1 and 2 shows up on the teechart
'If repeat the same to create Series 0, 1, 2, 3, 4, 5 all the six series are plotted
'For us a mulitiple of 3 series belong to one group
'so when we plot 2 or more groups the Series 0 becomes visible

'Chart is repainted and saved

Chart.Repaint()

Chart.Export.SaveToJPEGFile jpgChartFileName, false, 0, 100, chartwidth, chartheight

----------------------------------------------------------------------------

Hi Ravi,

I'm sorry, I cannot reproduce the problem here, simply simulating the code you post.

Code: Select all

Private Sub Form_Load()
TChart1.AddSeries scBar
TChart1.AddSeries scBar
TChart1.AddSeries scBar

Dim a, b
  a = Array(2, 3, 4, 5, 7, 1, 4, 5, 2)
  b = Array(4, 1, 8, 6, 2, 3, 3, 7, 1)

  TChart1.Series(0).AddArray 9, a, b
  TChart1.ChangeSeriesType 0, scLine
  TChart1.Series(1).AddArray 9, a, b
  TChart1.ChangeSeriesType 1, scLine
  TChart1.Series(2).AddArray 9, a, b
  TChart1.ChangeSeriesType 2, scLine
End Sub

Could you please send me an example with which I can reproduce "as is" the problem here ? (you can send me it directly to pep@steema.com).
