Hide/Remove labels NumericalAxis

[Herbert Moroni Cavallari de Costa Gois]

Hi!

I use NumericalAxis with custom labels defining positions

Ex.

"Peter" "John" "Anna"

It works great!

But when I use the zoom scroll bar labels appear like this:

"Peter" 1.2 1.4 1.6 1.8 "John" 2.2 2.4 2.6 28 "Anna"

i tried this:

OnZoomChanged(object sender, ZoomChangedEventArgs e)

        {

            ((SfChart)sender).PrimaryAxis.CustomLabels.ForEach(x =>

            {

                int integer;

                Int32.TryParse(Math.Round(x.Position).ToString(), out integer);

                if (integer == 0)

                {

                    x.Position = 0;

                    x.LabelContent = "";

                }

                else

                {

                    x.Position = x.Position;

                    x.LabelContent = x.LabelContent;

                }

            });

AND

OnZoomChanged(object sender, ZoomChangedEventArgs e)

        {

            ((SfChart)sender).PrimaryAxis.VisibleLabels.ForEach(x =>

            {

                int integer;

                Int32.TryParse(Math.Round(x.Position).ToString(), out integer);

                if (integer == 0)

                {

                    x.Position = 0;

                    x.LabelContent = "";

                }

                else

                {

                    x.Position = x.Position;

                    x.LabelContent = x.LabelContent;

                }

            });

But it works more or less

Hi Herbert,

Thanks for contacting Syncfusion support.

When we zoom the chart, the axis interval will be changed based on the zoomed chart area. In order to control the auto interval calculation on zooming, we have to set EnableAutoIntervalOnZooming property of chart axis as “False” as shown in the below code snippet.

Code snippet [XAML]:

<chart:SfChart.PrimaryAxis>

<chart:NumericalAxisInterval="1" EnableScrollBar="True"EnableAutoIntervalOnZooming="False">

<chart:NumericalAxis.CustomLabels>

<chart:ChartAxisLabelPosition="1"LabelContent="Peter"/>

<chart:ChartAxisLabelPosition="2"LabelContent="John"/>

<chart:ChartAxisLabelPosition="3"LabelContent="Anna"/>

chart:NumericalAxis.CustomLabels>

chart:NumericalAxis>

chart:SfChart.PrimaryAxis>
