[cfaussie] Re: cfchart on linux

[Gavin Cooney]

Hi Tim,   Well at least I know now that it's not just me!   #attributes.chart_format# is certainly png... it generates a valid png file when the name attribute is not passed to cfchart.   I suppose i could generate CF display the chart dynamically inside a cfsavecontent, and then search for the url of the resulting PNG by finding the IMG tag in the string and then use CFHTTP to get the chart. That's a pain tho.   Would lots of those cfhttps slow things down on the server?   I cant seem to find a technote or anything on macromedia about this. very strange.   Thanks for your help Tim.   Gav   ----- Original Message ----- From: Tim Lucas To: CFAussie Mailing List Sent: Friday, September 26, 2003 12:17 AM Subject: [cfaussie] Re: cfchart on linux Well I'm not sure what's in your #attributes.chart_format# but have you tried just: format="png" I tried this bit of code on MX and it works, on 6.1 it generates corrupt files <cfchart     format="png"     chartheight="300"     chartwidth="600"     name="piechart">     <cfchartseries         type="pie">         <cfchartdata item="Wicked Beat Sound System" value="328" />         <cfchartdata item="Dj Shadow" value="321" />         <cfchartdata item="Ltj Bukem" value="267" />         <cfchartdata item="Outkast" value="175" />         <cfchartdata item="Fatboy Slim" value="143" />         <cfchartdata item="Deep Forest" value="136" />         <cfchartdata item="Apollo Four Forty" value="129" />         <cfchartdata item="Marco V" value="120" />         <cfchartdata item="Transglobal Underground" value="119" />         <cfchartdata item="Supreme Beings Of Leisure" value="114" />         <cfchartdata item="Juno Reactor" value="112" />         <cfchartdata item="Caf? Del Mar" value="109" />         <cfchartdata item="Jurassic 5" value="107" />         <cfchartdata item="Air" value="102" />         <cfchartdata item="Dj Krush & Toshinori Kondo" value="96" />     </cfchartseries> </cfchart> <cffile     file="#ExpandPath('pie_chart_popular_artists.png')#"     action=""     nameconflict="overwrite"     output="#piechart#" /> On my CFMX6 win32 this works fine and generates a valid PNG or JPG file. On my CFMX6.1 win32 this generates a corrupt file for both PNG and JPG. If you let CFMX display it dynamically it works fine for both MX and 6.1 The two files can be downloaded here: http://www.toolmantim.com/pie_chart_popular_artists_6.png http://www.toolmantim.com/pie_chart_popular_artists_61.png Looking at the hexdump of the both files, MX is creating a valid PNG sig but 6.1 is not: MX:  89 50 4e 47 0d 0a 1a 0a 6.1:   3f 50 4e 47 0d 0a 1a 0a http://www.libpng.org/pub/png/spec/iso/#5PNG-file-signature I assume the first byte is probably corrupt for the JPG as well. Any ideas? - tim Gavin Cooney spoke the following wise words on 25/09/2003 3:21 PM EST: Hi all   I'm generating charts and saving them to disk using CFCHART on MX (not 6.1 just yet!). This is on a Linux box.   This code works fine to display the chart, but when i add the  name="chart_var" bit (saves the generated chart to a variable), it appears to work fine, but the generated chart seems to be in an invalid format. It wont open in a browser, and when i try to open it in Photoshop it comes up with "could not open [file] because the file-format module cannot parse the file.".   <cfchart  name="chart_var"  format="#attributes.chart_format#"  showlegend="no"  pieslicestyle="solid"  show3d="yes"  chartheight="200"  chartwidth="200"> <cfchartseries  type="pie"  query="online_answers"  valueColumn="count_answer"  itemColumn="answer_letter"  colorList="##fbf709,##333333,##ff5700,##cfc9c7,##ff0000"  paintstyle="shade"> </cfchart>   <cffile action="" output="#chart_var#" file="#application.online_chart_png_upload##saved_file_name#"> PNG file Written<br>   I'm sure this code worked before on this machine, and it works fine on my own PC.   Any ideas?   Gav --- You are currently subscribed to cfaussie as: [EMAIL PROTECTED] To unsubscribe send a blank email to [EMAIL PROTECTED] MX Downunder AsiaPac DevCon - http://mxdu.com/ --- You are currently subscribed to cfaussie as: [EMAIL PROTECTED] To unsubscribe send a blank email to [EMAIL PROTECTED] MX Downunder AsiaPac DevCon - http://mxdu.com/
