Discrete 3D Plot with date on one axis Could you tell us which data should be on x-, y-, and z-axis? Regarding the second question: Why don't you convert your dates to simple numbers (e.g. hours) and plot then these dates and v1 or v2 with ListPlot? then you see how v1 and v2 changes with time. |

Fit line similar to power of trendline in Excel Do you mean the axis origin? If yes, try something such as Show[ListPlot[data, PlotStyle -> Red, PlotRange -> All],
Plot[modelFit[x], {x, 10, 300}, PlotRange -> All],
AxesOrigin -> {0, 0}]. If this does not solve your problem, could you please describe it more detailed? |

Fit line similar to power of trendline in Excel Ok, just to summarize: The fit is ok, just the plot not. Do you agree? That is because you plot over a big range. If you use Show[ListPlot[data, PlotStyle -> Red, PlotRange -> All],
Plot[modelFit[x], {x, 10, 300}, PlotRange -> All]] you will see that the function fits to the data (without choosing such a big range as above). By the way: If you do not trust your fit, you can use something like Table[{i, modelFit[i]}, {i, 10, 30}]. If you compare the result with your data (or calculate the residual), you will see that the fit is well. |

Fit line similar to power of trendline in Excel Could you please give us the data too? Then we could try to get a better fit. |
