Hi,

I have problems with using ticks on an axis in Delphi. If I set the axis min/max values from code and I add some ticks, the axis does not use the min/max values anymore. How can I avoid this behaviour?

Next question is: how can I use the 'forceTickAt0' and 'forceTickAt100' from Delphi code? I did not find any sample code. I found it here:

http://www.jqplot.com/examples/axisScal ... ickAt.php#

Thanks in advance,
MS

Hi MicroSolutions,

It's a little complex component, so better, you provide us the simple testcase project to check what are you doing wrong (if case).

Best Regards.

Ok then, here is the simple question. How can I use the forceTickAt0 and forceTickAt100 options (see the following sample code) from Delphi:

$(document).ready(function(){
plot4 = $.jqplot('chart4',[makeContinuousData(20, 40, 5)], {
axesDefaults: {
pad: 0
},
axes: {
yaxis: {
rendererOptions: { forceTickAt0: true, forceTickAt100: true }
}
}
});
});

Thanks in advance,
MS

Hi,

At this moment, possible only with typecase:

delphi code

with IWCGJQPlot1.JQPlotOptions.Axes.Add do
  begin
    AxisType:= jqpoxyYAxis;
    Options.AxesRender:= jqparLinearAxisRenderer;
    (Options.AxesRenderOptions as TIWCGJQPlotLinearAxisRendererOptions).ForceTickAt0:= True;
  end;

We will implement the necessaries properties "links" in next beta build.

Thanks.

Best Regards.

Hi,

many thanks, this is exactly what I need!

Hi,

here is the sample code for the other question. So, there is a bar chart. If I add ticks on an axis, it won't use the Min/Max values anymore.

Without the ticks:



And with the added ticks:



And here is the sample code:

pascal code

procedure TIWForm1.IWAppFormShow(Sender: TObject);
var
  TempAxis: TIWCGJQPlotOptionsAxesItem;
  TempSeries: TIWCGJQPlotOptionsSeriesDefaults;
  I: Integer;
begin
  // Left Axis
  TempAxis := IWCGJQPlot1.JQPlotOptions.Axes.Add;
  TempAxis.AxisType := jqpoxyYAxis;
  TempAxis.Options.AxesRender := jqparLinearAxisRenderer;
  TempAxis.Options.Min := 0;
  TempAxis.Options.Max := 250;

  // Bottom Axis
  TempAxis := IWCGJQPlot1.JQPlotOptions.Axes.Add;
  TempAxis.AxisType := jqpoxyXAxis;
  TempAxis.Options.AxesRender := jqparLinearAxisRenderer;
  TempAxis.Options.Min := 0.5;
  TempAxis.Options.Max := 9.5;

// Remove the comments to add the ticks...
//  for I := 1 to 9 do
//    TempAxis.Options.Ticks.Add(IntToStr(I));

  TempSeries := IWCGJQPlot1.JQPlotOptions.Series.Add;
  TempSeries.Renderer := jqprBarRenderer;
  TempSeries.BarRendererOptions.BarWidth := 32;
  TempSeries.BarRendererOptions.VaryBarColor := True;

  IWCGJQPlot1.JQPlotData := '[[[1,225],[2,110],[3,195],[4,202.5],[5,155],[6,77.5],[7,192.5],[8,150],[9,145]]]';
end;

How can I avoid this behaviour?

Thanks in advance,
MS

Hi,

Define the TickInterval.

E.g:

delphi code

TempAxis.Options.TickInterval := 0.5;

Best Regards.

Well, it does not solve the problem. Any other solution?

Hi,

Well, it does not solve the problem.

Then I didn't realize your problem
Please try to explain better, and what are you expect.

Best Regards.
