= Methods = == Applet == See http://autoplot.org/applet_guide#Methods == WebStart == See http://autoplot.org/webstart_guide#Methods = Parameters = == Applet == * '''splashImage''' is the image to use as the preview as the applet initializes. * '''clickCallback''' is a javascript function to call with click info. <clickCallback>( plotid, xdatum, ydatum, xcanvas, ycanvas, clickType ) == Servlet == (from http://autoplot.org/servlet_guide): * '''format''' specifies the return format type ** image/png ** application/pdf ** image/svg+xml * '''script''' does nothing. The idea was an arbitrary script can be run giving complete control of the application, but because the ScriptContext is static (one per java instance), it cannot be supported. This will probably be corrected at some point. Also sandbox security needs to be ensured. * '''canvas.aspect'''. Aspect ratio for the canvas. Aspect is width/height, and simple expressions like '10/3' are handled. * '''process''' specifies a process to apply to the loaded data. ** histogram performs a 100-bin histogram on the data. The data is autoranged to establish min, max and scale type. ** magnitude(fft) displays the frequency content of the data == Common to Servlet and Applet == * '''width''' and '''height''' (servlet only--applets should specify width and height in <applet> tag.) * '''canvas.aspect''' servlet only, controls the ratio of the height to the width. * '''timeRange''' is the time range displayed. Using '''column''' and '''timeRange''' will allow for a stack of panels on the same time axis. * '''dataSetURL''' controls the initial URL displayed. Note "about:plugins" and "about:autoplot" are supported and useful for debugging. * '''column''' controls the horizontal layout. See [[help#layout]] * '''row''' controls the vertical layout. See [[help#layout]] * '''autolayout''' tells the applet to automatically adjust the row and column to avoid clipping labels. * '''font''' is the font to use on the system. This must identify a font on the client's desktop, so good choices are generic like "sans-16" * '''rendertype''' explicitly specifies how the data should be renderered ** scatter draws the data as a scatter plot ** series connects the plot symbols ** stairstep (used to be histogram) draws a stepped line to indicate the sample interval ** fillToZero (used to be fill_to_zero) uses a stairstep and fills to the reference line ** spectrogram renders the data as a spectrogram. Note if the data is not suited for this, nothing will be done. ** hugeScatter uses a faster rendering method that can handle millions of points. "series" and "scatter" start to dog at 40K points. * '''color''' specifies the plot symbol and symbol connector color * '''fillColor''' specifies the color used to fill to the reference * '''foregroundColor''' is the color of the axis and labels * '''backgroundColor''' is the color of the drawing canvas background * '''plot.title''' the title for the single panel plot. * '''plot.xaxis.label''' the label for the x axis. * '''plot.xaxis.range''' the range for the x axis. e.g. "2000-02-01 to 2000-02-15" or "200 to 800". With the servlet, pluses should be used in URLs instead of spaces. * '''plot.xaxis.log''' scale type for x axis. "true" indicates use a log axis * '''plot.xaxis.drawTickLabels''' "true" indicates draw labels. This is the default. * '''plot.yaxis.range, zaxis.range, etc''' controls for the yaxis and zaxis (colorbar). See with xaxis.*
