Change the appearance and properties of plots using:
- the Plot Properties window, or
- by sending commands to the plot visualizer from your Arduino sketch.
Plot Properties Window
Use the Plot Properties button () on any plot visualizer toolbar to open the plot properties window.
The properties available are similar for the different plot visualizers, differing only in the x-axis scale properties:
The title is shown above the plot. It is visible only when Show is checked.
SetTitle(…) method to change the plot title from your Arduino sketch.
The x-axis properties control the appearance and scale of the x, or horizontal, axis. Limits and tick spacing are set using date and time units for time plots and numeric values for x-y plots. In run-mode (tracking), set the duration visible on the x-axis for the time plot; MegunoLink calculates the limits automatically.
The x-axis title is shown below the plot. It can be hidden by un-checking the Show in the Plot Properties window.
SetXLabel(…) method to change the x-axis title from your your Arduino sketch.
The Minimum and Maximum values set the range of data displayed on the x-axis. When the Auto box is checked, the limits are calculated automatically to include all of the data available.
The Major Tick and Minor Tick values set the spacing between labelled and unlabeled ticks on the x-axis, respectively. Check the Auto box to calculate sensible values automatically.
The y-axis properties control the scale and appearance of the y, or vertical, axes. Two y-axes are available: one on the left of the plot and one on the right. Each axis can be visible or not and has an independent set of identical properties.
Controls whether the independent axis is visible or not.
Sets the title displayed next to the axes. No title is shown if Show Title is not checked.
The Minimum and Maximum values set the range of data displayed on the y-axis. When the Auto box is checked, the limits are calculated automatically to include all of the data available.
The Major Tick and Minor Tick values set the spacing between labelled and unlabeled ticks on the axis, respectively. Check the Auto box to calculate sensible values automatically.
Sets the color painted behind the plot area. The background is set as an angled, two color gradient. To create a solid fill, set both colors to be the same.
Maximum Number of Points
MegunoLink limits the maximum number of points in a series to prevent very large data-sets slowing your computer down.
By default, each series can contain up to 50,000 points. Old points are discarded to make way for new data when this limit is reached. This value can be increased to capture larger data sets or reduced to save memory and improve performance.
