When using TChartGrid I first assign all the multiple series generated to my ChartGrid. All still fine. When moving a data point (dragpoint) i set ChartGrid.Series to the series of the data point that I am moving. All still fine. When I disable the DragPoint feature and want to see all multiple seri...

I have a CSV file with multiple columns which I use to construct my graph. I use TSeriesTextSource and use only two columns (x, y) at a time. After editing the graph I would like to save the new data into the original CSV file replacing the selected columns with the new data and leaving the unused c...

How do get my left and bottom axis to have the same fixed increment withou resizing the chart on the screen For example x = -10, -5, 0, 5, 10, ... and y = -30, -25, 20, -15, -10, -5, 0, 5, 10, 15, 20, 30, ...... The pixels per increment should also be the same. I went into tools, and set the increme...

Thank you.

I am creating a TCurvFittingFunction at runtime. I wish to set the properties such as FirstPoint, Endpoint and PolyDegree. How do I do it. I used the following code. tmpPointSeries1:=TPointSeries.Create(self); AddSeries(tmpPointSeries1); //Populate them with data (here random) tmpPointSeries1.FillSa...

Thank you.

Row and Col are the two properties I never imagined would be used for this.

Thanks again.

Thank you.

Thank you very much.

Thanks for the code. I have used similar code. The problem is that it does not display data points towards the end of the graph unless you manually scroll to that point in ChartGrid. If you set the ChartGrid to display 10 points at a time and your series displays 100 points and you then select point...

I am attempting to deleting multiple points is a series. The code belows shows what I am trying to do. The problem is that it does not delete all the points. {*************************************************} procedure TFormPlot.chrtPlotMouseDown(Sender: TObject; Button: TMouseButton; Shift: TShift...

Thanks, but I am using TChart and TChartGrid and my series are created at runtime.

The link you directed me to seems to be for database entries only. By the way what is the name of Table1 component in the code.

When ever I click on a point on my series I want the row to be highlighted. I am able to do this using the ChartGrid1.Selection := myRect; property. The problem is that the row is not immediately visible. How can get this highlighted row to be visible immediately? And is using the code above the onl...

Thanks.

The works nice.

I also found that the values in columns 1 and 2 were a bit huge. When I used another huge data file (45000 entries) with smaller values my program was fine.

I have other issues at the moment but I will address as a new topic.

Thanks again.

Hi Narcis,

I have used the 2nd (x-axis) and 3rd (y-axis) columns.

To simplify the program you can use the TChart, TChartGrid and TSeriesTextSource. You have to converted the data file to a csv format prior to using it.

Hope this helps.

Thanks.

Hi there,

I have zipped the file this time around. Hope you can find it.

Thanks.
