10.1.2.2 The Data Info Window and Data Point Tooltip


Introduction

The Data Info window and Data Point Tooltips are related features that use similar dialog boxes to display similar descriptive information about a plotted data point.

  • Data Info: This is an older pop-up window that opens automatically when you choose either the Data Reader Button Data Reader.png, the Annotation Button Data Annotation.png, or the Data Cursor tool Button Data Cursor.png from the Tools toolbar.
  • Data Point Tooltip: is turned on, by default, and appears when you simply hover on a plotted data point.

User Story

In the image below, we have an automobile dataset comparing models from various manufacturers over a number of years. We begin by making a plot of Power vs. Gas Mileage and we want to do a little exploratory analysis using the resulting plot. We pick the Data Reader Button Data Reader.png from the Tools toolbar and click on a point in the graph that looks to be a bit of an outlier. The Data Info window opens and shows us that we have picked a point in row 334 or our worksheet and that it has coordinates of X = 66 (Power) and Y = 36 (Gas Mileage).

Data info columns controls 1.png

If we return to the source worksheet we find that row 334 happens to be a Saturn model, Year = 2004 and it has a rated Power = 66kw and a Gas Mileage = 36mpg. The Data Info window reports this information in its default configuration; but as we are doing our exploratory analysis, wouldn't it be helpful to know more than just X = 66 and Y = 36? What if, instead of reporting simple XY coordinates, we gave meaningful labels to the X and Y values? Also, wouldn't it be helpful to know automobile make and model and perhaps other available information about this data point (2004 Saturn) -- 0-60mph time, Weight and Engine Displacement? We can add this data to the Data Info window and even save our custom configuration for the next time we need to perform such exploratory analyses.

Data Point Tooltip

Starting with Origin 2019, you can simply hover on a data point to produce a tooltip that can be configured to report much the same information as the Data Info window. The tooltip is customized via the Data Point Tooltip dialog -- a slightly-simplified version of the Data Info Report Settings window. Use the documentation of the Data Info window, provided below, to configure the Data Point Tooltip dialog to show the information that you want to display in your tooltip.

Data point tooltip OH.png

To access the Data Point Tooltip dialog, hover on a point until the tooltip appears, then either (a) double-click on the tooltip or (b) right-click on the tooltip and choose Preferences.


There are a couple of ways to turn off display of the data tooltips (see next tip). The quickest way -- particularly if you find this feature useful but just want to temporarily disable it -- is to activate the graph and click the View menu. Clear the check mark beside with the graph window active.

There are two data tooltips, the other one being the older, non-customizable Data Plot Tooltip. You can toggle between the two or you can turn them off completely. To turn Data Point and Data Plot tooltips on or off, change the values of LabTalk system variables @PT and @PTI.

Data point vs plot tooltips.png
@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)

By default, the Data Point Tooltip displays with a moderate degree of transparency. You can affect tooltip transparency by changing the value of LabTalk System Variable @TDT. For information on changing the value of a LabTalk System Variable, see this FAQ.

Data Info Features

  • Highly customizable, both in its appearance and in the displayed content.
  • Can display data, metadata stored in the worksheet column label rows, and cell-embedded images.
  • A custom configuration can be saved to the graph window, to a single graph layer or even a single data plot.
  • A custom configuration can also be saved as a standalone file (Theme) and applied to yet-to-be-created data plots, at some later date.

Context Menu

Right-click on the Data Info window to bring up the context menu.

Row Controls

Generally, you will want your Data Info window to display the X and Y values (and Z if they exist) of your selected point. Use these buttons to add data point values to the Data Info window (or Data Point Tooltip).

When plotting numeric data, it is common for graph axis tick labels to be formatted differently than are the corresponding data in the source worksheet. In such cases, you can use either coordinate (e.g. Button X Coordinate.png) buttons and source buttons (e.g. Button Source X Data.png) for adding data point values:

  • If you choose coordinates, Data Info and Tooltips will follow the display format of the graph axis, but with more precision.
  • If you choose source, Data Info and Tooltips will follow the display format of the worksheet.

Note that in either case, you can still apply a custom format to Data Info or Tooltip display (i.e. you can set distinct formats for (1) worksheet, (2) graph axis and (3) tooltip dislplay) -- see Column Settings, below.

Type

Set what kind of information to show in the current column, options include:

  • Separator: Simply adds a narrow, empty column for space.
  • Labels: Show a column header from the source worksheet.
  • Value: Report the value chosen from the Source list.
  • Single Cell: This option merges all cells in the column into a single cell.
  • Numeric Display Format: Set the content to show in the current column. See Custom Numeric Formats.
Source

When Type =

  • Data (Reader)
  • Data Cursor (Cursor1, Cursor 2)
  • Relative (Reader - Cursor1, Cursor2 - Cursor1)
For information on using the Data Reader, see The Data Reader Tool. For information on setting Data Cursors, see The Data Cursor Tool.
  • Single Cell: The inserted column is a single cell that spans the height of the table. The cell displays a worksheet value determined by row index and the worksheet column that you have chosen in the Source list. Especially useful for displaying images and larger blocks of text.
  • Numeric Display Format: Inserts a column that is not used to display data but rather is used for formatting numeric data -- row by row -- in other columns in your table. If the default display format is not to your liking (e.g. number of displayed decimal places), you can use these controls to set numeric format, line by line, for your Data Info window or Tooltip:
  1. Click in a column cell and a list control is shown.
  2. Click on the list control to choose an appropriate custom format for your numeric data (note that this list merely shows examples and is not exhaustive); or type your custom format directly into the list control.
Data info custom format list.png

Date-time formats must be specified by entering "D" or "T", followed by a number N, where N corresponds with the format index (order, starting from "0") in the Display drop down list of the Column Properties dialog box (e.g. D0 corresponds with a display date of 9/17/2018).


Operates only on X, Y or Z data point values.

Source Affect X/Y/Z

Check this box to list source data by column Long Name, if it exists; otherwise list by Short Name. This box is automatically selected when you add source data to your table (i.e. you add data values using Button Source X Data.png).
