PsyChart Version 3 Recent Update History

Version Changes

Version 3.01.7 [9/8/2025]

  1. On the floating report windows (State Point, Process Energy, and Process Input/Output) added the units of each quantity to the column headers.

Version 3.01.5 [9/2/2025] (Official Release)

  1. Updated the sample projects to work with the released version and to be within the demo limits.

  2. Fixed a bug that could happen when moving a note or the chart bin legend when the Keep Aspect Ratio option for a chart was turned on, where if the main window was very close to being equal to the aspect ratio, it was possible for the note or legend to be positioned a little too far to the right or a little too low upon completing the move.

  3. Fixed a bug where the coordinate label alignments for the new coordinate types (dew point, vapor pressure and sensible heat ratio) were not being set to the default of Center Left upon opening a PsyChart version 2 project.

  4. Updated the help file to include the newest changes to the Chart Bins window and the chart bin legend on the chart.

Version 3.00.95 [8/29/2025] (Test Version)

  1. Fixed a bug where if you had added chart bins to a chart and had changed any of the values on the Chart Bins window to be different from the defaults, then when you created a new project or added a new chart to the current project, some of the values from the previous chart would carry over into the new chart.

  2. On the Chart Bins window, when any of the Months checkboxes were unchecked, made the Selected Hours label shows the exact number of hours based on each month's number of days (except for leap years).

  3. Added an optional "Dry Bulb Stats" section to the chart bin legend.

  4. Added the ability to move the chart bin legend by clicking it and selecting "Move" from the new popup menu.

  5. Added other items to the chart bin legend popup menu, including "Hide," "Show Dry Bulb Statistics," and "Dry Bulb Statistics Go from High to Low." Clicking any of these items immediately changes the legend.

  6. Removed Bin Count label and Create Example Bin button and inputs from Chart Bins window.

  7. Reduced the number of redraws happening when generating chart bins.

  8. When the license level is demo, added elevation check to the Chart Bins window to prevent trying to create bins for a city with elevation outside the demo limits.

Version 3.00.87 [8/13/2025] (Beta 2)

  1. On the Chart Bins window, if the current project has not had any chart bins created, made it so the last city shown in the "My cities with data" box is remembered the next time you open the Chart Bins window.

  2. Fixed a bug in the color assignments of chart bins, where the number of hours of a bin did not always correspond to the color in the legend.

  3. On the Properties at MousePointer toolbar (which shows the dry bulb, etc., at the current mousepointer position), added a tool to show the number of hours that occurred in the current chart bin, if the mousepointer happens to be over a chart bin.

  4. Fixed a bug in the creation of chart bins on the Chart Bins window, where if the Humidity Units input on the Chart Properties dialog was set to "Gr or kg" instead of "Fraction," then the chart bins would not be created.

  5. Added back the apparent white lines between adjacent chart bins, which were removed from the previous update, in order to more easily distinguish one bin from another.

  6. Fixed a bug in the creation of chart bins, where if the elevation was higher than the existing chart before chart bin creation the chart bins and chart would not correspond exactly to the Properties at Mousepointer values.

  7. Moved the default position of the chart bin legend to be closer to the top of the chart.

  8. Fixed a bug in chart bin creation where the elevation was not being converted from meters to feet for an English units chart, and the maximum dry bulb was not being converted to meters for a metric units chart.

  9. Fixed a bug where the chart bin width and height defined on the Chart Bins window were not being remembered the next time you open the window while in the same project.

  10. On the Chart Bins window, changed the "Add note with city name" option to include the elevation.

  11. Changed the included "Sample Chart Bins.ps3" project to Quito, Ecuador so that the elevation is within the range of the demo level of the program.

Version 3.00.82 [8/7/2025] (Beta 2)

  1. Fixed a bug where if you changed any of the properties on the Chart Properties dialog that require that all points and processes be deleted (Elevation, etc.), it would not also delete any existing chart bins that may have been created.

  2. Made adjustments to the vapor pressure and sensible heat ratio lines and labels.

  3. Changed the default dew point main coordinate line increment from 5 to 10 degrees in order to make the default chart's dew point labels not overlap each other near the bottom of the chart.

  4. Made an adjustment to the default sensible heat ratio coordinate line labels.

  5. Fixed a bug where the saved chart bins were not being restored upon opening an existing project.

  3. Added more sample projects.

  4. Fixed a bug where if the Chart Bins window was open and you then opened a project that has chart bins on the chart, the Chart Bins window did not automatically select the city used to create the bins.

Version 3.00.51 [6/23/2025] (TEST VERSION)

  1. On the Import Points tab of the Point Groups window, made it so if you enter zero for the "Starting number" input, the names of the points created will not have a numeral added as the suffix. Also added a dropdown help list item to let you select zero as the value.

  2. On the CSV File Grid tab of the Point Groups window, fixed a bug where the Save Grid to File button did not include the fixed header row in the saved file.

  3. Added a Keep Aspect Ratio feature that will keep the width to height ratio of the chart the same regardless of the width and height of the containing window. This feature can be adjusted or turned off on the General tab of the Chart Properties window.

  4. Added more coordinate lines and labels to the chart. These lines include dew point, vapor pressure, and sensible heat ratio.

  5. On the General tab of the Chart Properties window, added an option to show vapor pressure units as psi or in.Hg.

  6. On the General tab of the Chart Properties window, added an option to show the center point of the sensible heat ratio lines. That point is defined as 75 F dry bulb (or metric equivalent) and 50% relative humidity.

  7. Added a Chart Bins window, which lets you add bin rectangles with various colors to the chart that represent the number of hours that occurred in each bin the selected city. The weather data for about 3,000 cities throughout the world can be downloaded. A legend can be shown on the chart for the number of hours each of the bin colors represents.
