Hi, I've raised this issue before -please have patience. ******** (from TeeChart Help) Description If Axis.Automatic property is True, then the Maximum and Minimum values for the Axis will be automatically calculated based on all Axis dependent Series. ******** With TDBChart if the data has zeroes o...

Hi,

What's the best way to start a new line in the legend at any point, like -inserting a carriage return.

Will the legend width adjust itself afterwards?

Thanks,

Great. Problem cleared up. I didn't notice that a series in 'single record' mode needs to look at a TDatasource not the clientdataset. I was setting SeriesX.Datasource := cds at run-time. I assume from all this that 'single record' mode requires a TDatasource component. Thanks for your attention! Ba...

Actually I can get the minimum value with with the clientdataset aggregates function. -Not a problem.
Thanks

Thanks Narcis, Those methods won't work for me because the scale doesn't adjust. I think what I have to do is reset the axis minimum to the minimum Y value > 0 for each series. I could do this by looping through my clientdataset, finding the minimum positive value for each relevant column and using ...

Hi,

Is there a DBChart setting that will make TLineSeries ignore zero or null values so that the lines aren't bunched together at the top for larger Y values.

Thanks,

I'm afraid this came back to haunt me. I've created a set of Delphi project files if you want to have a look. I'm using D2005 with TeeChart Pro v7.05. Haven't noticed any particular difference between my code and your Single Record Demo code. I'm sure it's something extremely simple that I'm overloo...

Hi, Frequently my charts draw from clientdatasets whose contents I switch around for other datasets with different fieldDefs. I've learned to clear the data related chart properties to avoid error messages like: 'Project Alpha.exe raised exception class EdatabaseError with message'cds: Field 'fld1' ...

Sorry for the bother, this problem was related to other coding issues...

Thanks,

Turns out I had neglected to:

cds.EnableControls;

after having switched the dataset the grid and chart were drawing from.

Sorry for the uproar!

Hi,

Need some help figuring out why when I scroll through the DBGrid using the arrow key or the vertical scroll bar -the DBChart clears until I checkdatasource for all series?

Thanks for your insight,

Hi,

It appears that if you set the border style to 'Dot' in TLineSeries it will only appear as such if width = 1, else it appears solid.

Is there a way to get a dotted or dashed line with a pen width > 1?

Thanks,

Hi,

I have this:

Form1.Series8.YValues.ValueSource := 'mesh201;mesh202;mesh203;mesh204';

but the chart is displaying those 4 field values repeated for every record in the dataset.

If there are 15 records then 60 points are displayed in the chart.

Hoping for an explanation ...

Barry

Great, Thanks!!
