Axis Customization in ASP.NET Core Stock Chart control

22 Jul 2021 / 2 minutes to read

Axis Crossing

An axis can be positioned in the chart area using [crossesAt] (https://help.syncfusion.com/cr/aspnetcore-js2/Syncfusion.EJ2.Charts.StockChartStockChartAxis.html#Syncfusion_EJ2_Charts_StockChartStockChartAxis_CrossesAt) and [crossesInAxis] (https://help.syncfusion.com/cr/aspnetcore-js2/Syncfusion.EJ2.Charts.StockChartStockChartAxis.html#Syncfusion_EJ2_Charts_StockChartStockChartAxis_CrossesInAxis) properties. The [crossesAt] (https://help.syncfusion.com/cr/aspnetcore-js2/Syncfusion.EJ2.Charts.StockChartStockChartAxis.html#Syncfusion_EJ2_Charts_StockChartStockChartAxis_CrossesAt) property specifies the values (datetime, numeric, or logarithmic) at which the axis line has to be intersected with the vertical axis or vice-versa, and the [crossesInAxis] (https://help.syncfusion.com/cr/aspnetcore-js2/Syncfusion.EJ2.Charts.StockChartStockChartAxis.html#Syncfusion_EJ2_Charts_StockChartStockChartAxis_CrossesInAxis) property specifies the axis name with which the axis line has to be crossed.

Title

You can add a title to the axis using titleproperty to provide quick information to the user about the data plotted in the axis.Title style can be customized using titleStyle property of the axis.

Tick Lines Customization

You can customize the  width, color and size of the minor and major tick lines, using majorTickLines and minorTickLines properties in the axis.

Multiple Axis

In addition to primary X and Y axis, we can add n number of axis to the chart. Series can be associated with this [axis] (https://help.syncfusion.com/cr/aspnetcore-js2/Syncfusion.EJ2.Charts.StockChartAxis.html), by mapping with axis’s unique name.

            public double y1;
        }

Inversed Axis

When an axis is inversed, highest value of the axis comes closer to origin and vice versa. To place an axis in inversed manner set this property isInversed to true.

Opposed Position

To place an axis opposite from its original position, set opposedPosition property of the axis to true.
