viscosity representation following ASTM D 341

[anyel]

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

Make a column of numbers, take the logs, put them in the next column, do the same with values in rows. Use those values to plot against log-log.

Excel does allow log-log plots. After you create a plot click on the axis to get the menu box, select "format axis", and the select the log scale.

How would you do it before there was an Excel?

goto

(downloads) and you will find a spreadsheet solution with the data graphed. The graphical results is defaulted to linear/linear but if you want to adapt this send an email for the passwords.

excel plots log scale, but no double log scale. The target is to create the astm 341 chart in excel. It´s a conversion chart, with interlines distance fixed. To reproduce this chart to obtenin the viscosity-temp straight line of a fluid , the axis "x" in excell would be log(T) and "y" log(log(v+0.8), in other way it is obtained a curve chart. the only problem is that it should be done the conversion to know any viscosity to any temp.

big inch: i would do it manualy in the astm chart and scanning it

very thanks to all for your usefull and quick response

anyel, Are you clear on how to do that in XL now?
