I have included my code. It has tabs so it doesn't look so good here. The second procedure calls the first one two times. This is very customized for my application, but the main issue I have is that when you turn marks on/off, the axis limits need to be recalculated so that the marks fit on the cha...

My problem is that I can't call SetMinMax until after there is a valid ChartRect value (because I use ChartRect to detemrine the plot limits), but then after my call to SetMinMax I need the chart to be recreated using my new limits. For example, if the chart is resized, I need the new size to be pla...

It looks like you are assuming four pixels per character, but that won't always be the case.

In addition, using this event will be slow when there are a large number of points. It would probably work if only the labels being displayed triggered the event, but that isn't the case.

Hi, I have the same problem, and setting the LabelsSize to a constant isn't a workaround to the bug. There needs to be a way to calculate how much space is used, and then add some to that. Is there a way to determine the amount of space that is allocated to the axis labels so that we can add a littl...

To be more specific, I modified the TeeChart Pro v7.06 VCL / CLX version source code.

International character support

Hi,

I've changed ten lines of Tee Chart Pro source code and now have full international character support. Is anyone interested in this?

Regards,

I was setting up axis properties such as LabelsSize, RoundFirstLabel, and Increment, and calling SetMinMax.

TCustomChart.CalcAxisRect

Hi,

I'm finally getting around to converting my application to using TeeChartPro 7, from the TeeChart that came with Delphi 7, which I'm still using.

I had been overriding the CalcAxisRect method, but it doesn't exist in TeeChartPro 7. Does anyone know what I should use instead?

Regards,

Bill
