Thanks very much! Here is a sample dataset I'm trying to plot. Using the evaluation version of Fusion Charts 3, the y-axis extends to -3 instead of stopping at 0 as specified in the chart attribute. <chart alternateVGridColor="CCCCCC" showBorder="0" alternateHGridColor="CCCCCC" yAxisMinValue="0" divLineColor="888888" baseFontColor="666666" alternateVGridAlpha="20" defaultAnimation="0" alternateHGridAlpha="20" bgColor="FFFFFF" xAxisMaxValue="10" divLineAlpha="50" canvasBorderThickness="1"> <dataset anchorAlpha="0" showValues="0" drawLine="1" color="#eec446"> <set x="0.5" y="-0.6931471805599453"/> <set x="1" y="0"/> <set x="1.5" y="0.4054651081081644"/> <set x="2" y="0.6931471805599453"/> <set x="2.5" y="0.9162907318741551"/> <set x="3" y="1.0986122886681097"/> <set x="3.5" y="1.252762968495368"/> <set x="4" y="1.3862943611198905"/> <set x="4.5" y="1.5040773967762741"/> <set x="5" y="1.6094379124341002"/> <set x="5.5" y="1.7047480922384252"/> <set x="6" y="1.791759469228055"/> <set x="6.5" y="1.8718021769015913"/> <set x="7" y="1.9459101490553132"/> <set x="7.5" y="2.0149030205422646"/> <set x="8" y="2.0794415416798357"/> <set x="8.5" y="2.1400661634962707"/> <set x="9" y="2.1972245773362195"/> <set x="9.5" y="2.2512917986064953"/> <set x="10" y="2.302585092994046"/> </dataset> <dataset anchorAlpha="0" showValues="0" drawLine="1" color="#afd8f8"> <set x="2.5" y="-0.3862943611198906"/> <set x="3" y="1"/> <set x="3.5" y="1.8109302162163287"/> <set x="4" y="2.386294361119891"/> <set x="4.5" y="2.83258146374831"/> <set x="5" y="3.1972245773362195"/> <set x="5.5" y="3.505525936990736"/> <set x="6" y="3.772588722239781"/> <set x="6.5" y="4.008154793552548"/> <set x="7" y="4.218875824868201"/> <set x="7.5" y="4.4094961844768505"/> <set x="8" y="4.58351893845611"/> <set x="8.5" y="4.743604353803183"/> <set x="9" y="4.891820298110627"/> <set x="9.5" y="5.029806041084529"/> <set x="10" y="5.1588830833596715"/> </dataset> <dataset anchorAlpha="0" showValues="0" drawLine="1" color="#cb4b4b"> <set x="1.5" y="-1.70816136715364"/> <set x="2" y="-0.09953876174499299"/> <set x="2.5" y="0.7377352846277348"/> <set x="3" y="1.2821434828500972"/> <set x="3.5" y="1.6760544604778846"/> <set x="4" y="1.9799027799348427"/> <set x="4.5" y="2.224539054478355"/> <set x="5" y="2.4276549859813316"/> <set x="5.5" y="2.600252059996497"/> <set x="6" y="2.749594242347978"/> <set x="6.5" y="2.8807050932181295"/> <set x="7" y="2.9971894317348293"/> <set x="7.5" y="3.1017131964318283"/> <set x="8" y="3.196298104259336"/> <set x="8.5" y="3.2825102382323354"/> <set x="9" y="3.3615850245299334"/> <set x="9.5" y="3.434512552537589"/> <set x="10" y="3.502097335743868"/> </dataset> <dataset anchorAlpha="0" showValues="0" drawLine="1" color="#4da74d"> <set x="0" y="1"/> <set x="0.5" y="1.05"/> <set x="1" y="1.1"/> <set x="1.5" y="1.15"/> <set x="2" y="1.2"/> <set x="2.5" y="1.25"/> <set x="3" y="1.3"/> <set x="3.5" y="1.35"/> <set x="4" y="1.4"/> <set x="4.5" y="1.45"/> <set x="5" y="1.5"/> <set x="5.5" y="1.55"/> <set x="6" y="1.6"/> <set x="6.5" y="1.65"/> <set x="7" y="1.7000000000000001"/> <set x="7.5" y="1.75"/> <set x="8" y="1.8"/> <set x="8.5" y="1.85"/> <set x="9" y="1.9"/> <set x="9.5" y="1.9500000000000001"/> <set x="10" y="2"/> </dataset> <dataset anchorAlpha="0" showValues="0" drawLine="1" color="#9440ed"> <set x="0" y="3"/> <set x="0.5" y="2.75"/> <set x="1" y="2.5"/> <set x="1.5" y="2.25"/> <set x="2" y="2"/> <set x="2.5" y="1.75"/> <set x="3" y="1.5"/> <set x="3.5" y="1.25"/> <set x="4" y="1"/> <set x="4.5" y="0.75"/> <set x="5" y="0.5"/> <set x="5.5" y="0.25"/> <set x="6" y="0"/> <set x="6.5" y="-0.25"/> <set x="7" y="-0.5"/> <set x="7.5" y="-0.75"/> <set x="8" y="-1"/> <set x="8.5" y="-1.25"/> <set x="9" y="-1.5"/> <set x="9.5" y="-1.75"/> <set x="10" y="-2"/> </dataset> <styles> <definition> <style alpha="30" name="MyShadow" type="Shadow"/> </definition> <application> <apply styles="MyShadow" toObject="DATAPLOT"/> <apply styles="MyShadow" toObject="CANVAS"/> </application> </styles> </chart>

Adding, the proposed workaround of setting values less than the yminvalue to be equal to yminvalue is not acceptable, because it alters the slope of the line segment that crosses the line x=yminvalue. So for example if I'm plotting the points [1,-1], [2,1], [3, 3] with yminvalue=0, I would expect to see a straight line segment clipped by the edge of the chart at x=1.5, but with the proposed solution, I see a line that "bends" at [2,1] to produce a line segment that terminates at x=1 instead. I hope that I haven't confused my explanation too badly
