ASTM D 341 chart representation 1

hi everyone,
do someone know about a program to draw the loglog viscosity followed in this code??? excell does not allow a loglog draft.

thanks in advanced

Excel can display graphs with logarithmic scales on both axes. Are you entering negative numbers for temperature? Change to Kelvins.

Try

go to the ASTM D341 reference and follow the Viscosity Calculation link.
Open to the chart and click the axis and you should be able to change to log.

You could also download the graph paper generators at

http://www.printfreegraphpaper.com/

and plot the 40/50⁰C and 100^OC data and draw a straight line fit as per the ASTM D341 directions (I seem to recall that there are examples in the standard)
