Only on X axis 1285 <li>Integer scale. X and Y axis 1286 </ul> 1287 1288 Any combination of these may be used. Linear and logarithmic scales are pretty straightforward. The text scale might deserve some explanation. The easiest way to think of the text scale is as a linear scale consisting of only natural numbers, i.e. 0,1,2,3,4,? . This scale is used when you just have a number of Y-values you want to plot in a consecutive order and don?t care about the X-values. It is also used when you need to have text labesl you specify (via $graph->xaxis->SetTickLabels($labels) ). 1289 <p> 1290 To specify which combination of X and Y scales you want to use the $axtype parameter is specified. In this parameter you specify, by a text string, the type of scale you want to use for both X and Y scale. 1291 <p> 1292 Possible values for each axis are:<br> 1293 X: 'lin', 'text', 'log', 'int'<br> 1294 Y: 'lin', 'log', 'int'<br> 1295 <p> 1296 Example of possible combination:<br> 1297 <ul> 1298 <li>SetScale('textint'); 1299 <li>SetScale('loglog'); 1300 <li>SetScale('linlog'); 1301 </ul> 1302 It is normally recommended to use the auto-scaling feature since for most practical purposes it is good enough. However on rare occasions you might want to specify the limits yourself. This is then done by the rest of the parameters to the method. 1303 <p> 1304 Note: If you want to use a logarithmic scale you must make sure that the ?jpgraph_log.php? is included. 1305 <p> 1306 <b>Note1:</b> 1307 Note that if you manually specify the scale you can also specify the tick distance with a call to Ticks::Set(). For example $graph->yaxis->scale->ticks->Set(10,5) If yiou don't ste it manually a suitable tick distance will be automatically choosen. 1308 1309 <b>Note2:</b> 1310 If you want to keep the autoscaling for Y-axis but specify the X-axis then just call the method with both min and max set to 0 (e.g. SetScale('linlin',0,0,0,50); ) 1311 1312 <br> 1313 <div

Instead the Stroke() method will simply return the image handle used by the GD library. This can come in handy of you like to post manipulate the image or use the raw GD image in other context. Such as in creating dynamic PDF documents. 1677 <p> 1678 Note: If you want to use the image in a PDF file you can't take the handle directly since this is a GD handle. To use it in PDF you must first create an PDF image by calling pdf_open_memory_image() to get a proper PDF image handle. See example below. 1679 1680 <p> 1681 You may also specify the file name as "auto" in which case the filename will be created from the script name but with the extension changed to reflect the choosen image format. 1682 <br> 1683 1684 <div style="font-weight:bold;font-family:arial;font-size:85%;"><p>Example</div><span style="font-family:courier;font-size:85%;"><font color="#000000"> 1685 // Example 1 : (Normal case) Stream back to browser <br />$graph->Stroke(); <br /> <br />// Example 2 : Stream to the file with absolute file path <br />$graph->Stroke($fileName); <br /> <br />// Example 3 <br />// Get the image handle.

This method does not send back an image to the browser but rather a HTML page which contains an image map and a "recursive call" back to the image script. See the full JpGraph manual for a detailed explanation on how this works. 1719 <p> 1720 Please note that it is abolutely imperative that you specify the image generating scripts name as the first argument. 1721 <p> 1722 Why that? Because it is impossible for JpGraph to find out the name of the script it is executed from in the case where it is included as oart of a "standard" HTML/PHP page. Using the PHP_SELF will only return the master document and not the actual script name. 1723 <p> 1724 If you use several image map images on the same HTML page you must also specify unique names of each of the image maps as the second argument for this function. 1725 <p> 1726 To specify targets for the image maps you must call the individual plots Pot::SetCSIMTargets() 1727 <p> 1728 Tip: You can easily specify the script name by using the construction 1729 basename(__FILE__) as the first argument <br> 1730 <div style="font-weight:bold;font-family:arial;font-size:85%;">See also</div><a href="Plot.html#_PLOT_SETCSIMTARGETS">Plot::SetCSIMTargets</a> 1731 <div style="font-weight:bold;font-family:arial;font-size:85%;"><p>Example</div><span style="font-family:courier;font-size:85%;"><font color="#000000"> 1732 ... <br />$graph->StrokeCSIM(basename(__FILE__)); <br /></font> 1733 </span><br> 1734 <p> 1735 <p> <p> <span style='font-size:110%;'><a name="_GRAPH_STROKEFRAMEBACKGROUND"><div style="border-top:solid black 2pt;background-color:lightblue;font-family:courier new;font-size:90%;font-weight:bold;"><b><font color="#000000"> 1736 function StrokeFrameBackground()</font> 1737 </b></div></a></span> 1738 1739 <span style='font-family:arial;font-size:90%;'><i>Stroke the frames background and border</i></span><p> 1740 <br> 1741 1742 <div style="font-weight:bold;font-family:arial;font-size:85%;">Description</div>Semi Internal routine.
