ChronoPlotter supports creating graphs comparing bullet seating depth and group size.
Table of contents:
ShotMarker
Click the Select ShotMarker file button and select your ShotMarker .tar or .csv file:
The program should now be populated with all of your recorded data:
Uncheck any strings you don’t want to include in the graph. Then enter a cartridge length for each series, or click the Auto-fill cartridge lengths button to automate the process:
To include details in the graph about the components used in testing, additionally fill in the text fields on the right:
Clicking Show graph pops open a new window with a preview of the generated graph. Note: This does not save your graph, only displays it.
The graph will look something like this:
By default, ChronoPlotter displays the ES (Extreme Spread) for each shot group in the graph. A variety of other statistical measurements such as Y-Stdev, X-Stdev, Radial Stdev (RSD), and Mean Radius (MR) can be selected with the Group size measurement option.
Close the preview window, making sure not to close ChronoPlotter itself. Finally, click Save graph as image to save your graph as a .PNG, .JPG, or .PDF file.
Special thanks to Brian Li for the assistance in adding shot dispersion measurements to ChronoPlotter.
Manual data entry
Begin by clicking the Manual data entry button:
By default, a single empty series is created. Click the Add new group button to create additional series for each cartridge length being tested. Then enter a cartridge length for each series, or click the Auto-fill cartridge lengths button to automate the process:
Then proceed to enter the group size for each series. NOTE: ChronoPlotter defaults to CBTO (Cartridge Base to Ogive) for cartridge length and ES (Extreme Spread) for group size measurements. Other measurements may instead be selected under the Graph options section on the right, if desired.
To include details in the graph about the components used in testing, additionally fill in the text fields on the right:
Clicking Show graph pops open a new window with a preview of the generated graph. Note: This does not save your graph, only displays it.
The graph will look something like this:
By default, ChronoPlotter displays the group size for each series in the graph. The series-to-series difference in group size can also be displayed but is unchecked by default. You can add, remove, or change the location of these details in the graph under the Graph options section.
Close the preview window, making sure not to close ChronoPlotter itself. Finally, click Save graph as image to save your graph as a .PNG, .JPG, or .PDF file.
