Modifying Display of Charts

In-chart functions can enhance the way the charts are displayed. The in-chart functions can be used across all chart types.

To view these in-chart functions, you must select a chart and the icons for these functions are displayed as you hover the cursor over the chart. Notice that the cursor is displayed as a crosshair within the chart region. To understand the working of the in-chart functions in a better manner, let us consider the histogram chart for the field sepal_width.

Hiding / Showing Chart Using Legend Info

A legend is displayed for each chart you plot. You can use the legend to modify your chart's display. The legend provides you the following info:

  • All values—The values in a field, which are plotted in blue, by default for all chart types.
  • baseline—The baseline data, which are plotted in brown, displayed only when you set baseline using the Configure Dataset feature.
  • Selection—The selected region, which is plotted in red or blue (depending on the chart type), displayed only when you select a region on the chart using the Box Select feature.
  • Explanation—The values covered for explanation, which are plotted in green or blue cross (depending on the chart type), displayed only when you analyze a selected region on the chart using the Explain feature.

With a single click, you can hide / show the plotted data associated with one or more of these legends. If you choose to hide the data, the legend entry appears subdued. For example:

  1. If you click the All values legend, the chart display is modified in the following manner.

  1. If you click the baseline legend, the chart display is modified in the following manner.

  1. If you click more than one or all the legends to hide the data, the chart is modified in the following manner:

4. To restore the chart display, click each (subdued) legend again.

Using in-chart functions

The in-chart functions are explained in the order marked in the following image. Notice that the icon for the active function appears brighter than the others. Click any icon once to activate the corresponding function. By default, the Zoom function is enabled.

  1. Download as png—Lets you download the plotted chart in .png file format. The KS6800A software uses the browser settings to download the file either to the default location or to a specific folder location. By default, the file is named by the KS6800A software as newplot.png.

  1. Zoom—Lets you enlarge a specific area of the plotted chart. With the zoom in-chart function selected, click anywhere within the plotted area and drag the cursor to select the portion you wish to enlarge.

The area marked for zoom is enlarged accordingly, as shown below.

Click outside the chart to remove the zoomed in view, as shown below.

  1. Pan—Lets you move the chart around inside the plotting window, so that you may view the chart from a specific direction (either left or right). For example, the image below shows that the plotted chart, which was enlarged earlier, has been moved up to analyze the lower regions of the chart.

  1. Box Select—Lets you select the chart in part or full. Click and drag the crosshair top-down to select one or more elements in a chart, as shown in the image below.

The selected region appears in red, as shown in the example below.

You can perform a lot of other actions on a selected region of the chart. For more information about such actions, see Selecting Data on Charts.

  1. Zoom in—Lets you enlarge the chart display on the whole (in a uniform manner), instead of enlarging a specific region of your choice (as described in Zoom function). Here, you have to click the icon for Zoom in each time you wish to enlarge the chart display.

  1. Zoom out—Lets you shrink the chart display on the whole (in a uniform manner). Here, you have to click the icon for Zoom out each time you wish to shrink the chart display.

  1. Reset axes—Lets you restore the chart display to the original view. It removes any modification made to the chart.

  1. Toggle log x axis—Lets you toggle logarithmic x axis, depending on the chart type.
  • On Histogram charts—This function is available only if all values on X axis are either positive or negative, that is, none of the values must cross the zero level.
  • On Pareto charts—This function is not available.
  • On Box and Whisker charts—This function is not available.
  • On Scatter / Summary Line charts—This function is available only if all values (of the added field) on X axis are numeric and all of them must be either positive or negative, that is, none of the values must cross the zero level.

  1. Toggle log y axis—Lets you toggle logarithmic y axis, depending on the chart type.
  • On Histogram charts—This function is available as all values on Y axis are numeric, by default.
  • On Pareto charts—This function is available as all values on Y axis are numeric, by default.
  • On Box and Whisker charts—This function is available only if all values on Y axis are either positive or negative, that is, none of the values must cross the zero level.
  • On Scatter / Summary Line charts—This function is available only if all values (of the added field) on Y axis are numeric and all of them must be either positive or negative, that is, none of the values must cross the zero level.
