Axes Features

The default Chart Control settings includes the the primary axes-X and Y. The Chart Control framework also provides complete support for the inclusion of multiple X and Y axes.

Horizontal and vertical gridlines can be included in the chart area to bring clarity to the data points on the chart.

The appearance of gridlines can be customized as illustrated below:

The appearance of the X and Y Axes lines can be customized to fit your needs. The style, width and color of these lines can be defined.

Essential Chart supports major and minor axis tick-marks on the chart axes. The appearance of the tick-mark can be customized by changing its color, height and width.

The number of minor axis tick-marks between the major axis tick-marks can also be specified.

The axis label text can be custom defined by setting the size, color and font of the label text in Chart Control.

The orientation of the axis labels can be rotated to any specific angle. This is useful when labels are long and might overlap.

Essential Chart can be configured to automatically rotate labels to avoid overlap by setting the ChartLabelIntersectionActionEffect property to Rotate.

Essential Chart lets you obtain a custom plot. The data points can be plotted about any specific X or Y-axis value, or a data point.

Striplines are bands that can be drawn horizontally or vertically on the chart background to highlight certain regions. The strip lines can also be repeated (to mark weekends, for example).

The comfort level of the human mind decreases, when grasping the multiples of 3,7,11 when compared to 5,10,15. A similar effect can be felt when calculating ranges for the ChartControl. Keeping this in mind, the ChartControl has been implemented with an automatic range scaling engine, that will synthesize the best possible range for a given set of values.

Automatic range calculations are also configurable. You may configure a range to start with 0 and may also set the preferred number of intervals.

Automatic ranges are also calculated for date values. The range intervals are calculated to be in increments of easily understandable date segments, such as weeks, months, years, etc.

Nice Dates in ChartControl

Essential Chart lets you specify a custom range and its scale for the axis if the automatically calculated range scale is undesirable. You can set the range as well as the intervals of an axis.

Custom x-axis range with minimum value '0', maximum value '6' and an interval of '1', and custom Y-Axis range with minimum value '-100', maximum value '600' and an interval of '100' is illustrated below:

Essential Chart supports opposed position of chart axes. The axis on the chart can be positioned opposite to that of the default axis position. This is useful in creating RTL charts or charts with negative values.

This feature also comes handy when working with multiple axes, where you could position the secondary axis opposite to that of the primary axis.

Any chart axis range can be reversed and the data for this axis is plotted in the opposite direction. A chart with inverted axes is shown in the illustration. The range is rendered:

• Top to bottom in Y axis
• Right to left in X axis

Essential Chart supports multiple axes. You can add a secondary axis and position it side-by-side or below the primary axis.

These options are illustrated below:

You can also position this secondary axis opposite to the primary axis as shown below.

Essential Chart supports logarithmic axes. The data type of any series that is plotted on the chart can be set to Logarithmic. Both the Axes of Chart Control can be customized to display Logarithmic values.

You can also specify custom logarithmic axis ranges for the chart.

Scale breaks help in accommodating outlying data into the display while also clearly displaying normal values. Scale breaks can be applied automatically or manually.
