| Nov 5, 2020 at 5:32 | comment | added | Wolfgang Bangerth | Separate point: Never create graphs in which you show $\ln(x)$ and $\ln y$ on the axes. Nobody knows what $x$ corresponds to $\ln(x)=9.2$ (the last cross-over point). Instead use a log or loglog plot. All reasonable software has this. It uses a logarithmic scaling of the axes, but the labels printed next to the axes are of $x$, not $\ln(x)$. | |

Small corrction in grid numbers

| Jul 17, 2015 at 11:25 | comment | added | Doug Lipinski | Could you please clarify what error metric you are using and which finite difference formulas? One sided differences? | |
| Jul 17, 2015 at 6:32 | comment | added | AGN | I have linked this question in answer to that question. | |
