(Approx cloud height is a calculation from pressure and humidity) Instead of shading the area under graph value I want to shade above the value up to 100% of scale in a sky blue. I was going to simply use a CDEF to calculate the diff between actual value and 100% of scale and trend this via a stack. My question is that the real value I want to be totally transparent so I only see the sky blue colour in the upper part of the trend. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Is there a hex colour value for totally transparent ?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>It would be really cool if the upper “sky” blue area of the graph actually shows some random white clouds within this area so it really looks like sky. I don’t know if I could achieve this via a CDEF anybody have any idea’s of how I could achieve a cloud shape object within this upper area randomly within the time line. I assume its again a stack command however really need it as a random shape “cloud looking”. An alternative maybe to simply generate the graph then use imagemagic to insert clouds within the upper graph area.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any idea’s<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cheers<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Rob Australia<o:p></o:p></p></div></body></html>
