Hi,

How can I set the number of labels that must appear in the graph meter?

I am using the graphical meter and if the labels are overlapping , making the visualization of values

Below is the code generator :

var grafico1 = new RGraph.Meter('grafico1', 0, 4187662.3, 4186662.30);
grafico1.Set('chart.red.start', 0);
grafico1.Set('chart.red.end', 391500);
grafico1.Set('chart.yellow.start', 391500);
grafico1.Set('chart.yellow.end', 783000.00);
grafico1.Set('chart.green.start', 783000.00);
grafico1.Set('chart.green.end', 4187662.3);
grafico1.Set('chart.gutter.bottom', 25);
grafico1.Set('chart.gutter.left', 35);
grafico1.Set('chart.gutter.right', 25);
grafico1.Set('chart.gutter.top', 25);
grafico1.Set('chart.labels.above', false);
grafico1.Set('chart.labels.above.decimals', 0);
grafico1.Set('chart.scale.point', ',');
grafico1.Set('chart.scale.thousand', '.');
grafico1.Set('chart.shadow', true);
grafico1.Set('chart.shadow.blur', 15);
grafico1.Set('chart.shadow.color', '#000000');
grafico1.Set('chart.title', 'PRIMEIRO TURNO');
grafico1.Set('chart.title.vpos', '0.6');
grafico1.Set('chart.linewidth', 1);
grafico1.Set('chart.linewidth.segments',0);
            
grafico1.Draw();
}


<canvas id="grafico1" width=500px height=250px>[No canvas support]</canvas>

Hi

The number of labels for the Meter is fixed at ten you could modify the source if you wanted to - the relevant for loop is in the drawLabels function.
