Can't plot 3d graph

Kota · January 14, 2020, 10:14am

(I’m sorry my English is bad.)

Dear All.

I attempted plotting 3d-graph to show error-value about some analysis.
I wrote this code, but can’t plot graph (the output figure is only 1 black line).

gmt psbasemap -JX12/12 -JZ12 -R6.5/9.0/2.0/4.5/0.003/0.004 -Bagf -BWSNEZ -p220/20/0 -X2 -Y3 -K > output.ps
gmt psxyz -JX -JZ -R -Sc0.3c -Gred -p220/20/0 << END -O >> output.ps
8.1000004 	4.5000000 	0.0033251 
8.1999998 	3.2000000 	0.0033287 
7.8000002 	4.3000000 	0.0033349 
8.0000000 	3.7000000 	0.0033394 
END

I know this problem may be caused by using very small z-values, so could you teach me how I should modify this script?

Any help would be highly appreciated.
Thanks.

No surprise they all fall in a same level. z in your points only differs slightly in the 5th decimal place.

I appreciate your response!

Is there a way to plot xy-level with keeping z-values? or should I use Microsoft Excel?

Thanks.

But that’s what you did no? Maybe the symbol size was too big. Or am I missing the issue?

I appreciate your reply
In actuality, there are more data I want to plot. (The data is at the bottom)

I can plot the figure by Excel.

But, GMT can’t plot x&y axis, like this. (I don’t need lines between the point such as Excel figure)

Is it caused by using very small z-values? or I wrote wrong scripts?
