minor ticks at arbitrary positions logarithmic scale?

First of, excuse my ignorance of logarithmic scales, but I have a very specific request regarding minor ticks. My client want a graph with a different number of minor ticks according to different decades. For example, if the decade is less than 1 he wants 10 labels(1, 2, 3, 4, 5, 6, 7, 8, 9, 10) and...

Re: Hiding series in Chart Editor

Hi Yeray Thanks for your reply. Note that all 3 series have the same data and settings (line color, symbol, line type, etc) as appropriate. The LineSeries is used only to show the legend - its DataSource is set to nil just before the chart is drawn so no data is plotted. The legends of the FastLineS...

Re: Hiding series in Chart Editor

Further to my previous submission, I see that the HideInEditor code does not hide the FastLine and Point series but does hide the LineSeries. Without the code, all 3 series are shown in the editor.

Hiding series in Chart Editor

To better control symbol placement for dense data sets, I create a LineSeries, a FastLineSeries and a PointSeries for each set of data. The LineSeries is used only for the legend, while the other two series show the line and the points respectively. I have a lot of custom code to format the resultin...

NVidia Graphics Conflict

I recently released a new version of one of our applications, developed with Delphi 2007 and TeeChart 8. New code included use of draggable marks. A user has reported a conflict on computers running NVidia graphics (program crashes on exit). Has this been reported before?

Legend Items Show/Hide

In my application, multiple line series are plotted with a fairly standard legend (line type, symbol and series name derived from the key field values in the database). The graph also has two special series. How can I easily show and hide the legend entries just for these series while leaving all se...

Custom draggable marks with auto-scaling axis

I am using Delphi 2007 and TeeChart Pro 8.06. I wish to position marks to the right of each point in a LineSeries (rather than above) and then allow them to be draggable. I clearly cannot use a Chart.OnAfterDraw event as this will be triggered whenever I try to drag the marks and reset them to the d...

Installing TeeChart 8

I am trying to update Delphi from V 7 to V 2007 (R2) and Tee Chart from V 7.07 to V 8.01. I first installed Delphi 2007. I then ran TeeRecompile.exe which created DclTeePro811.bpl and DclTeeProStd811.bpl. I started Delphi, opened dlcTeeProStd811.dpk and DclTeePro811.dpk and successfully built each o...
