Scroll arrow locked

Hello,
I'm trying to make the scroll arrow to go only where there is value in the series. In Delphi works with the lock, when the series finish.
I read in the tutorial 08 the instructions, but I could not.
I did something wrong?
The following code:
Code: Select all
JFrame frame = new JFrame();
JPanel panel = new JPanel();
panel.setSize(600, 600);
TChart chart = new TChart();
chart.getAxes().getBottom().getLabels().setValueFormat("0");
panel.add(chart);
Bar bar = new Bar(chart.getChart());
for (int i = 0; i < 10; i++) {
bar.add(i);
}
AxisArrow axisDown = new AxisArrow(chart.getChart().getAxes().getBottom());
axisDown.setScrollInverted(false);
chart.getChart().getTools().add(axisDown);
chart.getAxes().getBottom().setAutomatic(false);
chart.getAxes().getBottom().setMinimum(0.0);
chart.getAxes().getBottom().setMaximum(10.0);
frame.add(panel);
frame.setSize(600, 600);
frame.setVisible(true);

Hello,
Are you sure you are doing the same in Delphi and in Java?
The following code, in Delphi, doesn't "lock" the axis for me here:
Code: Select all
uses Series, TeeTools;
procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
Chart1.View3D:=false;
with Chart1.AddSeries(TBarSeries) do
for i:=0 to 9 do
Add(i);
(Chart1.Tools.Add(TAxisArrowTool) as TAxisArrowTool).Axis:=Chart1.Axes.Bottom;
end;

Hi Yeray,
I'm doing in Java.
I want to lock the scroll when it came to the limits of the series.

I understood you are trying to do it in Java, but I also understood you already achieved it in Delphi:

So I was trying to see how did you do that in Delphi. I'd say it will probably be similar.

I translate from Delphi to Java, but it did not work as I wanted, so I asked here.
In java it does not block the scroll when the series ends.
It would be a problem? Or am I doing wrong?

Hi WhebJava,
Code below works fine for me here. Can you please check if it works fine at your end?
Code: Select all
private void initChart() {
commander1.setChart(tChart1.getChart());
final Line l = new Line(tChart1.getChart());
l.fillSampleValues();
final AxisArrow axisDownLeft = new AxisArrow(tChart1.getChart().getAxes().getBottom());
axisDownLeft.setPosition(AxisArrowPosition.START);
final AxisArrow axisDownRight = new AxisArrow(tChart1.getChart().getAxes().getBottom());
axisDownRight.setPosition(AxisArrowPosition.END);
tChart1.addChartPaintListener( new ChartPaintAdapter() {
@Override
public void seriesPainted(ChartDrawEvent e) {
boolean leftActive = false;
boolean rightActive = false;
if (l.firstDisplayed() > 0) {
rightActive = true;
} else {
rightActive = false;
}
if (l.lastDisplayed() < l.getCount() - 1) {
leftActive = true;
} else {
leftActive = false;
}
axisDownLeft.setActive(leftActive);
axisDownRight.setActive(rightActive);
};
@Override
public void chartPainted(ChartDrawEvent e) {
//
};
});
}
Thanks in advance.

Hi Narcis,
It is something similar to what you did have to do.
I will make the necessary changes, thanks for the tips.
