Run Time plot is getting disturbed while saving

[biswasdibyendu]

I have completed the analysis using GUI of Zonation but one problem I am facing during saving the "Prop. of Distribution Remaining Vs Cost needed to achieve given conservation value". Just after running the analysis, the graph is being shown properly, but the moment I am doing Right click to save it as pdf the line becoming parallel to the x-axis. Attaching the picture.
