1.221 FAQ-972 Can I modify the tooltips that appear when I hover on data plots in my graph?
Last Update: 9/13/2018
Origin 2017 introduced a Data Plot Tooltip that appears when you hover on a data plot in the graph window. The Plot tooltip is fairly basic, reporting source book, sheet and coordinate datasets. It is not customizable.
Beginning with Origin 2019, there is a second tooltip that shows, by default, for many 2D plot types. This we refer to as the Data Point Tooltip to distinguish it from the Plot tooltip. The Data Point Tooltip is highly-customizable.
The Data Plot Tooltip can be displayed for most plot types. The Data Point Tooltip is, as mentioned, supported only in 2D graphs. In plots that support both types of tooltips, you can switch between the two by right-clicking on the tooltip and choosing from the shortcut menu.
Enabling or Disabling Tooltips
To turn Data Point and Data Plot tooltips on or off, change the values of LabTalk system variables @PT and @PTI.
@PT=0; //Disable both data plot and data point tooltips
@PT=1; //Enable data plot tooltips for 2D graph (default)
@PT=2; //Enable data plot tooltips for 3D OpenGL graph
@PT=3; //Enable data plot tooltips for both 2D graph and 3D OpenGL graph
@PTI=0; //Disable only data point tooltips
@PTI=1; //Enable data point tooltips (default)
Modifying Tooltip Transparency
You can also modify the degree of transparency of the tooltip using the system variable @TDT. You may want to do this if, for instance, you have modified your Data Point Tooltip to display imagery. @TDT is set to 220, by default. Lower the value to increase transparency or set it to 255 to disable transparency.
