Load, plotdef, and plot behave as you describe, thanks for familiar behavior.
For plot (;*:) steps 0 3 200 and Chrome web browser, There is no straight line segment running from the last point of the curve to the first -- thanks! 8 in y-axis label looks like 3 . In other plots with two-digit y-axis labels only the second digit shows. y-axis labels are being cut off on the left. Grid lines are very faint. For plotdemos 34 and Chrome web browser Horizontal labels col 1 col 2 col 3 are cut off at bottom so o looks like n . Vertical labels row 1 row 2 row 3 run into y-axis labels so that label row 2 interferes with 1 and 2 of y-axis labels 100 and 200, and label row 3 interferes with 50 of y-axis label 5000 . Numerical y-axis labels are complete: they are not cut off at left as described above for plot (;*:) . The 5 of 5000 y-axis label for column 2 is inside the plot for column 1, and likewise the 5 of 5000 for column 3 is inside the plot for column 2. The columns should be spaced farther apart horizontally. Hope this helps. You have chosen a large task for one person to do!
