Plotting Images and Data
Mira provides tools for plotting images in various 1-D and 3-D formats, including intensity profiles, line cuts, histograms, radial intensity profiles, contours, and surface plots. Tools are also provided for plotting data tabulated in the Grid Control of a Report Window or Measurement Pane. These commands originate in the Image Plot Toolbar, Grid Command Menu, and other menus.

Mira provides several ways to display data in the form of a graph. For this, Mira AL x64 provides both the Plot window interface and the Chart window interface as shown below. Plots are often created to show the relationship between image luminance and position, known as a Profile Plot, but several other plot types are available for images.

A Profile Plot is a graph of pixel values along a line through an image. This line may be parallel to the column direction, parallel to the row direction, or along an arbitrary direction. These are referred to as a Column Profile, Row Profile, and a Line Profile, respectively. Mira can plot not just a line of row or column data but also an average column or row or all columns or rows. In addition, if an image set is opened, you can choose to plot these quantities for every image in the set. Mira can create plots showing data in the following forms.
Several of these commands can be operated using a single keystroke command.
The Column Profile command graphs image luminance along an image column.
The Row Profile command graphs image luminance along an image row.
The Radial Profile command graphs luminance versus distance in all directions around a point in an image.
The Line Profile command graphs image luminance along an arbitrary drawn line.
The Histogram command graphs the frequency of occurrence of different luminance values.
The following commands work with table data in a Grid Control:
The Create Plot from Table Data command plots two columns of data from the table into a Plot Window.
The Create Chart from Table Data command plots two columns of data from the table into a Chart Window.
