Hi,

I need to find out how to autowrap a header text which might be too long for the width of the chart? W/o setting the autowrap on, the header text line gets truncated if it's too long.

Hope I've said the issue clearly enough.

Thanks.

Hi,

you can calculate the width of the Text that must be added and depending on it use more that one line using :

Code: Select all

textWidth = tChart1.Canvas.TextWidth("my text")

With TChart1
    .Header.Text.Remove (0)
    .Header.Text.Add "My First Line"
    .Header.Text.Add "My Second Line"
End With

I do the following in my VC++ code:

Code: Select all

long canvas_width = m_chart.GetCanvas().GetWidth();
long text_width = m_chart.GetCanvas().TextWidth(very_long_text_string);
m_chart.GetHeader().GetText().Add(COleVariant(very_long_text_string));

When I set the header text with the string above, the text goes off the chart on the left and right side. However, the value of canvas_width is greater than text_width. This doesn't make sense to me. How can I accurately compare the header string length against the chart width?

Thanks.

Hi jonnyg,

Could you please send us a simple example project we can run "as-is" to reproduce the problem here?
