RE: [ cf-dev ] CFChart performance

[Ellwood]

Using Flash charts you can click on the drivers names to remove them using the click thru methods. I have never used them yet so cannot comment on their effectiveness but I guess it is just a case of passing a variable through to the next page which removes the driver from the series. Might be worth investigating for your needs.   Ellis C Wood BSc Ellwood Web Solutions   T: 01623 459973 E: [EMAIL PROTECTED] W: http://www.ellwoodwebsolutions.co.uk -----Original Message----- From: Giles Roadnight [mailto:[EMAIL PROTECTED] Sent: 29 March 2004 11:41 To: [EMAIL PROTECTED] Subject: RE: [ cf-dev ] CFChart performance   Blimey – yes just downloaded one of the swf’s and it is 100 odd k!!! swf is supposed to be a small quick to download format but in this case the swf is a lot bigger than the jpg. Surely they can make it smaller than this – the data wouldn’t take that much space up.   Very tempting to make my own and just pass it some xml with the data in….   Possibly a future project.   Giles Roadnight http://giles.roadnight.name   -----Original Message----- From: Giles Roadnight [mailto:[EMAIL PROTECTED] Sent: 29 March 2004 11:38 To: [EMAIL PROTECTED] Subject: RE: [ cf-dev ] CFChart performance   OK, I am broadband and it’s not as if it takes ages to appear just longer than I expected. Anyway, thanks for putting my mind at rest.   Shame we can’t get to the source of the swf and change it – I would like to add the option to click on Drivers names to remove them form the graph (it gets a bit busy) and to add a pre-loader. I could make my own fla but that would be a lot of work to add this minor feature and I would not have the option of easily switching to jpg is the user does not have flash.   I tried the non-flash version and the images do appear pretty quickly so must just be the size of the swf’s.   Non-flash version: http://www.arccc.org/results/index.cfm?fuseaction=displayRace&raceID=457&flashdetect=false   flash version:   http://www.arccc.org/results/index.cfm?fuseaction=displayRace&raceID=457&flashdetect=true         Giles Roadnight http://giles.roadnight.name   -----Original Message----- From: Ellwood [mailto:[EMAIL PROTECTED] Sent: 29 March 2004 11:21 To: [EMAIL PROTECTED] Subject: RE: [ cf-dev ] CFChart performance   Giles,   Just had a look at your graphs and…..well…..it is little wonder they take a massive 2seconds to download. There is a lot of data there, 9 series and about 16 datapoints each. I wouldn’t worry about it mate. Have you tried outputting them as jpg or png to see if that has any load performance difference.   Charts offer a great way of quickly seeing data in a visual format that is much easier for us humans to interpret and from what I have seen on your site, there is little to be concerned about. It could however, be your connection speed. I have broadband so I would expect it to be quick but that said, it does rule out the CF Server performance if I can see it within 2 seconds.   Regards   Ellis C Wood BSc Ellwood Web Solutions   T: 01623 459973 E: [EMAIL PROTECTED] W: http://www.ellwoodwebsolutions.co.uk -----Original Message----- From: Giles Roadnight [mailto:[EMAIL PROTECTED] Sent: 29 March 2004 10:57 To: [EMAIL PROTECTED] Subject: [ cf-dev ] CFChart performance   I am using cfchart to produce a couple of graphs here:   http://www.arccc.org/results/index.cfm?fuseaction=displayRace&raceID=457   But they take a while to appear. Is this because the server is generating them each time the page is called? Is it just the swf download time (would have thought the sw’fs are quite small). Are cfcharts cached at all?   Any help / advice appreciated.   Giles Roadnight http://giles.roadnight.name
