2d Line Series Outline Color

AndrewK · Post by **AndrewK** » Fri Jan 07, 2005 11:18 pm

I can't get the outline color to work using a 2d line chart with Steema 5.

Here is the code I'm using:

m_oTChart.Series(i).asLine.outline.visible = true
m_oTChart.Series(i).asLine.outline.width = 1
m_oTChart.Series(i).asLine.outline.color = vbBlack

The outline shows up and with the proper width but it shows up only with the color used for m_oTChart.Series(i).Color

Hi AndrewK,

Which TeeChart version are you using? Your code works here using latest releases of v5, v6 and v7 ActiveX.

We're using v5 in ASP pages.

Also, the outline color works when the chart is 3D, but not when it is 2D.

Hi AndrewK,

Here it works ok using maintenance release v5.06, are you using this version? If not you can download it from our Customer Download Area.

If it is still not working could you please send us an example that we can run "as-is" to reproduce the problem here? You can send the example to our steema.public.attachments newsgroup.

I can't extract and provide a working set of code very easily. But, here is some additional info which I hope is helpful:

If I populate the line series with the FillSampleValues method the outline works (oChart.Series(i).FillSampleValues 10).

If I populate the line series with the Add method I encounter the problems I've mentioned above (oChart.Series(i).Add).

I can't find the attachment newsgroup anywhere.

Here is an example which demonstrates the problem I'm having. Please let me know what I should be doing instead.

Hi Andrew,

I see what happens here, to make it work you must set the Color of the series in the following manner, instead of setting a color for each point you add :

Code: Select all

for j = 0 to ubound(arrSeriesData) 
arrSeriesDataPoints = split(arrSeriesData(j), ",") 
if arrSeriesDataPoints(0) <> "" then 
oChart.Series(i).Add CDbl(arrSeriesDataPoints(0)), arrLabels(j), clTeecolor 
oChart.Series(i).Color=GetCustomColor(arrSeriesDataPoints(1))
 if arrSeriesParams(0) = "scLine" then 
 oChart.series(i).asLine.outline.visible = true 
 oChart.series(i).asLine.outline.color = vbBlack 
 end if 
end if
