Description: |
Using the xconfig or yconfig command with the -scale option results in an "Unknown or invalid value" error. Script showing problem: package require Tk package require Plotchart canvas .c pack .c set s [Plotchart::createXYPlot .c {0 100 10} {0 100 10}] $s xconfig -scale {0 200 20} The problem is in Plotchart::AxisConfig, in the file plotaxis.tcl around line 492. The "idx" value is the index into a list with a single value per option, and it is used to index into the axis_option_values which has two values per option. One possible fix is to multiply the idx by 2 before using it on the axis_option_values. set clear [lindex $axis_option_clear $idx] >> set idx [expr {2 * $idx}] set values [lindex $axis_option_values [incr idx]] Also, in the plotaxis.tcl file there is "console show" and "puts" command in the Plotchart::DrawXaxis routine which seem out of place. Thanks, -paul | |||

Fixed in version 2.3.3: A call to worldCoordinates was needed to reset the scaling, so that the values are mapped to the appropriate screen coordinates. arjenmarkus added on 2008-03-07 14:39:38: Logged In: YES user_id=400048 Originator: NO I have been looking into this: - The fix you suggest solves the immediate syntactical problem - The scale values for the axis remain unchanged though - you get the same axis back. - When I fixed that bit, I got strange results (the wrong range, only a part of the labels I expected drawn). - The code as it is is too naive: I need to change a few private variables in the scaling array as well (they hold the transformation from world coordinates to pixels) arjenmarkus added on 2008-02-28 15:31:15: Logged In: YES user_id=400048 Originator: NO The console show/puts commands are already gone - they were indeed way out of place, except for debugging purposes ;). The -scale option is more serious: I will look into this. Thanks for reporting it. |
