Summary

This portlet allows to create an interactive chart as line chart, bar chart, or area chart. Other than the Chart (Portlet) it does not import a chart previously created in TIS Editor, but builds the chart itself.

It provides features like switching data series on and off, zooming in and out, or export as .xls file.

TIPS

Note the possibility of zooming in to display details (see Working with EJS-Chart). (Note that using the zoom function of the browser can cause rendering problems.)

Scalable y-axis

The y-axis can be scaled manually. Go to the EJSChart Settings within the Portlet Designer, check the box next to "Scale Manually" and define the minimum and maximum value.

Formatting

Using % as a symbol multiples values with 100.


For different formats it is possible to manually enter a format string (see help box). E.g., the string "DDD, dd.MM.yyyy" will produce a format like "Mon, 01.01.2016".

See also Formatting strings.

Markings

The markings can be defined by the number of markings

or by the spacing between each marking:
