ich habe folgendes Problem. Ich möchte einige Messwerte unter LaTeX darstellen und dazwischen eine "Kurve" interpolieren.
Soweit funktioniert dies sehr gut, doch die Kurve ist nicht schön "flüssig".
Hier das Minimalbeispiel:
\documentclass[11pt,fleqn,numbers=noenddot]{scrartcl} \usepackage[ngerman]{babel} \usepackage{pgfplots,pgfplotstable} \usepackage[locale=DE]{siunitx} \usepackage{pdflscape} \usepackage{nicefrac} \pgfplotsset{ compat=newest, xlabel near ticks, ylabel near ticks } \begin{document} \begin{landscape} \begin{tikzpicture} \begin{axis}[ title={$\Phi$-$V_{Umlauf}$-Kennlinien}, width=1.5\textwidth,height=0.9\textheight, axis x line=bottom, xmin=0, xmax=820, xtick={0,80,160,240,320,400,480,560,640,720,800}, axis y line=left, ymin=0, ymax=0.0021, ytick={0,0.0001,0.0002,0.0003,0.0004,0.0005,0.0006,0.0007,0.0008,0.0009, 0.001,0.0011,0.0012,0.0013,0.0014,0.0015,0.0016,0.0017,0.0018,0.0019,0.002}, xlabel={$V_{Umlauf}$ in $\left[\si{\ampere}\right]$}, ylabel={$\Phi$ in$\left[\si{\volt\second}\right]$}, grid=major, legend style={ at={(current bounding box.north-|current axis.east)}, anchor=east, legend columns=3 } ] \addplot+[color=red,smooth] coordinates { (0,0) (80, 0.0005) (160, 0.0009) (240, 0.0011) (320, 0.0013) (400, 0.0014) (480, 0.0015) (560, 0.0015) (640, 0.0016) (720, 0.0016) (800, 0.0017) } ; \addlegendentry{Case 1} \addplot+[color=blue,smooth] coordinates { (0,0) (80, 0.0001) (160, 0.0003) (240, 0.0003) (320, 0.0004) (400, 0.0006) (480, 0.0006) (560, 0.0008) (640, 0.0009) (720, 0.0010) (800, 0.0011) } ; \addlegendentry{Case 2} \addplot+[color=green,smooth] coordinates { (0,0) (80, 0.0001) (160, 0.0001) (240, 0.0002) (320, 0.0003) (400, 0.0004) (480, 0.0005) (560, 0.0005) (640, 0.0006) (720, 0.0006) (800, 0.0007) } ; \addlegendentry{Case 3} \addplot+[color=brown,smooth] coordinates { (0,0) (80, 0.0000) (160, 0.0001) (240, 0.0001) (320, 0.0002) (400, 0.0003) (480, 0.0003) (560, 0.0004) (640, 0.0004) (720, 0.0005) (800, 0.0005) } ; \addlegendentry{Case 4} \addplot+[color=black,smooth] coordinates { (0,0) (80, 0) (160, 0.0001) (240, 0.0001) (320, 0.0001) (400, 0.0002) (480, 0.0002) (560, 0.0003) (640, 0.0003) (720, 0.0003) (800, 0.0004) } ; \addlegendentry{Case 5} \legend{$\nicefrac{\delta}{2}=0$\\$\nicefrac{\delta}{2}=0,5$\\$\nicefrac{\delta}{2}=1$\\$\nicefrac{\delta}{2}=2$\\$\nicefrac{\delta}{2}=4$\\} \end{axis} \end{tikzpicture} \end{landscape} \end{document}
