Can you advise on best way to add a flat line on a standard XY chart please. I have charts which have X=increment of samples 1 through N000, and a single variable that varies in y axis. I want to put a line at a specified tolerance, say at y=6, so there is a flat line from x min to x max of chart. I...

How do I add null data to a colorgrid series, there does not seem to be a .addxyznull() method

thanks
Sean

.....ongetpointerstye behaves of valueindex does not count null data. eg. if series values are 0..100, but all odd indexes are null, then ongetpointerstyle only gets activated for 50 of the 0..100 points, those that are not null. Is that correct?

I'm using a chart with many tlineseries, and am colouring individual points on each series with ongetpointerstyle. Works fine except when the series hold null values. data is array of x,y,z (z is a variable value, eg. water depth) if some_condition then chart.series[series_no].AddXY(x,y) else chart....

Is it possible to addnull to a Tseriescolorgrid ?

thanks Narcis, v 7.07 here as well. I wondered if maybe there was a property buried somewhere which straps the legen point size to the point size used on the chart. In another project I've got the legend size remains fixed as required, but in the project under qwuestion I can't get the legend size n...

D6Pro, Tchart 7, line series which draws points at X,Y on a Tchart. I can control the size of the points with with chart.series[0] as tlineseries do Pointer.Size:=vesselshotsize.Value; However, the point size of the symbol shown in the legend also tracks this, so if my point size is 1 you can't see ...

I have about 30 Tcharts on a form each with several Tlineseries plotting as time-series. (TChart 7.07, Delphi 6 Pro, Win XP). The t.series can contain several thousand points, and I and provide the user the option to lock zooming so that a zoom on chart1 is reflected across all charts on the form. I...
