April Webinars: Chart Challenge with DataGraph!

This month we have been inspired by the #30DayChartChallenge on Twitter. The challenge has five overall categories and each day has a specific theme. To participate, all you need to do it post a graph using #30DayChartChallenge that is inspired by the theme of the day. Here are the DataGraph […]

Text Formatting

When DataGraph displays a text, from a text box, a tokenized field or a data column, it applies the formatting as defined in the Style settings, including font size, bold, italics, and color. In addition, the program will look for commands in the text string that alter the format, draw […]

Data Input

Manual Input DataGraph has four primary column types. To create any of these columns under the Data menu. For example for a number number select Data > Add Number Column or use the shortcut Command-1. When you enter in the data table, the following rules are used: Double-click on a cell […]

Scalar Field Basics

The Scalar Field command allows you to apply colors, contours, or labels using data that is mapped to an x-y grid. Add a Scalar Field Select Command > Add Scalar Field to add the scalar field command. Example 1 Given a data set with three numerical columns, x, y, and […]

Scalar Field Examples

The Scalar field command works with two-dimensional regular grids. Regular Uniform Non-uniform Rectilinear Curvilinear Grid Download the example files to see how the following graphs are made. Uniform Grid The Scalar Field is used to represent a 10×10 uniform grid of data in three columns (x,y,z). A Color Ramp variable […]

How to add Error Bars

Several plotting commands have the option of adding error bars including: Plot, Points, Bar, and Bars. Key Features: Set the style of the error bars Set the direction of the error bars Vary the magnitude of the bars in any direction NOTE: These examples assume you have the value for […]

Database Connection

Beta version only This is currently only enabled in the beta. This is still under development. Any issues or questions, please contact us for further support. GOAL: Make it easy to connect to a database and download all or a subset of the data. Make it easy to update the […]

Webinar: Creating Scalar fields in DataGraph

Scalar fields are two dimensional representations of data, functions, or physical quantities across a surface. For example, topographical maps are a common example of a scalar field, where the elevation at a given x,y location is represented by varying the color. Join us while we explore examples using the new […]

How to Sort a Column

Columns can be sorted individually, or one column can be used to sort multiple columns at once. To change the sort order in the data table: Right click on a column heading (or click the gear menu in the column list) Select Sort (Increasing or Decreasing) Select from the sort […]

Number from Text

This column type allows you to extract a number value from a text column, to create a new number column. Text Select the text column. Location Select the location of the numeric value you want to extract from the text column. Type Decimal = a numerical value Hexadecimal = convert […]
