android axis labels change position (move up)

[NIS]

hello,

I need move some labels on bottom axis above the axis line and some labels should stay below. But i didnt found solution, please help.

Or is there some handler for drawing series? because in monotouch-teechart-lib. i found handler but not in java lib.

Same problem with series Marks, i want set different arrow length for each mark in series .

Thanks.

What event did you use in TeeChart MonoTouch (now TeeChart .NET for Xamarin.iOS)?

Same problem with series Marks, i want set different arrow length for each mark in series .

Have you tried doing something similar to this?

monotouch solution:

chart.Axes.Bottom.GetAxisDrawLabel += new Steema.TeeChart.GetAxisDrawLabelEventHandler(Bottom_GetAxisDrawLabel);

int count = 0;

void Bottom_GetAxisDrawLabel (object sender, Steema.TeeChart.GetAxisDrawLabelEventArgs e)
{
if ( values [count] > 0.0) {
e.Y = (int)(chart4.Axes.Left.CalcYPosValue(0.0)-8);
}else if ( values [count] < 0.0 || values [count] == 0.0) {
e.Y = (int)(chart4.Axes.Left.CalcYPosValue(0.0)-21);
}
count++;
if(count == values.Count) count = 0;
}

So,

thanks for your help, you solved my problem with marks.

And there is reason why i need move Label over the axis line.

(picture is in post over)
and i noticed that one more small problem is with ticks:

chart.getAxes().getBottom().getTicks().setLength(0);
chart.getAxes().getBottom().getTicks().setColor(Color.white);
chart.getAxes().getBottom().getTicks().setUsesVisible(false);
chart.getAxes().getBottom().getTicks().setVisible(false);

chart.getAxes().getBottom().getTicksInner().setLength(0);
chart.getAxes().getBottom().getTicksInner().setColor(Color.white);
chart.getAxes().getBottom().getTicksInner().setUsesVisible(false);
chart.getAxes().getBottom().getTicksInner().setVisible(false);

-> nothink works
(
but maybe problem can be that i have added into custom labels:
chart.getAxes().getBottom().getCustomLabels().add( 0.0, "12/12" );
)

Hi,

The only way I can think to work around this is to hide those labels that correspond to negative values with the AxisLabelResolver. And you could use the same event to manually draw the labels where you want.
Something like this:

Code: Select all

		tChart1.setAxisLabelResolver(new AxisLabelAdapter() {
			
			@Override
			public String getLabel(Axis axis, ISeries s, int valueIndex, String labelText) {
				if (axis == tChart1.getAxes().getBottom()) {
					if (valueIndex == -1) {
						for (valueIndex=0; valueIndex<tChart1.getSeries(0).getCount(); valueIndex++) {
							if (tChart1.getSeries(0).getXValues().getValue(valueIndex) == Double.parseDouble(labelText)) {
								if (tChart1.getSeries(0).getYValues().getValue(valueIndex) < 0) {
									int x = axis.calcPosValue(tChart1.getSeries(0).getXValues().getValue(valueIndex)) - (tChart1.getGraphics3D().textWidth(labelText) / 2);
									int y = tChart1.getChart().getChartRect().getBottom() - 15;
									tChart1.getGraphics3D().textOut(x, y, labelText);
									return "";
								}
							}
						}
					}
				}
				
				return labelText;
			}
		});
