Function Reference

Functions can be used anywhere in DataGraph that accepts numerical values. Use them in Expression variables or Expression columns. Function input can be numbers, variables, or column names. Functions operate on individual values or values within the same row, or row operations. For column operations, see the list of built-in […]

Plot Action

Use the Plot Action column to perform mathematical actions on columns of data. Create the Plot action columns using the Other drop-down menu above the column definitions. To use this action, the first step is to select the x and y input columns. The next step is to select the […]

Binary columns

This column type stores numbers as IEEE binary numbers. This differs from the number column that stores the textual representation entered in a column and converts that to a number when you open the DataGraph file. For example, if you enter ‘1/10’ in a binary column it gets converted to […]

Date columns

The Date column type is intended for calendar dates and understands a variety of formats. Below is a Date column entry as it is shown in the column definition list. Converting to Dates Unlike many spreadsheet applications that autodetect date entries and may even change the underlying data when dates […]

Style settings

At the top of the settings is the Style settings, with an icon that looks like an artist palette. Overview In the style settings, you can set the font, line, and point styles, in terms of both size and colors. This is a top-down or style sheet approach. For example, […]

Canvas settings

The Canvas settings contain options for customizing the drawing area and the graph title. This includes setting the size, background colors, and margins. Size By default the graph size is set to ‘Automatic’, meanging that the size is fills the area included by the sliding bars. It is better to […]

Axis settings

The Axis settings are the third object in the layout settings, under the Style settings and the Canvas settings. Using this object, you can add labels, control the type, change the axis range, and customize the tick marks. Note that several of the axis settings can be modified directly from […]

Column Properties

Column properties are a handy way to build mathematical expressions using a range of numbers, specifically a column of values.  To refer to them, type the name of the column followed by a ‘.’ and the property name.  For example, ‘name.sum’ returns a single value, the sum of a column. […]

Expression column

The Expression column allows you to compute and derive numerical values.

Text columns

The Text column is intended for labels or categorical data. Below is a Text column entry as it is shown in the column definition list. Values Menu There are a number of commands and options that will accept only numerical data as input, such as the Plot and the Points […]
