QC SPC Chart Free Version

The QC SPC Chart software is an interactive SPC chart (6-sigma) application aimed at quality control professionals (and students) who want to view industry standard statistical quality control charts on their mobile devices. Typical users will monitor critical quality factors in manufacturing, process, and service industries, and display the results in one of the many supported chart types. Chart types include: variable control charts (XBar-R, XBar-Sigma, Individual-Range, and Median-Range), and attribute control charts for monitoring defects (p-, np-, c-, u-, and DPMO charts). The software will automatically calculate SPC control limits using historical data for the supported variable control chart and attribute control chart types. Alarms can be generated for standard +3 sigma control limits, or the WECO (Western Electric) rules. It will also calculate process capability ratios (Cp, Cpk) and process performance indices (Pp, Ppk). A set of specification limits can also be added to the chart.

The SPC charts are displayed as one or two synchronized charts, under the control of a scroll bar. The scroll bar can be replaced by an integrated zoom control which allows for the display of charts with a custom time frame. Auto-scaling of the charts y-axes keeps everything in view. An integrated table appears above the chart, that displays information about the process under view, and each sample interval plotted in the chart. The table displays time, individual sample values, sample statistics, process indices, alarm status, and any notes entered for that sample interval.

The user can customize the SPC chart and control limits using built-in setup forms. Both auto-calculated and manually set control limits are supported. The user can manually input and edit sample data from within the program. The user can also import sample data from a CSV (comma separated value) file. The entire chart setup, and data, can be saved on the host device so that they are easily accessible the next time you use the app. You can even set the current setup to be auto-loaded the next time the app starts.

The software displays a lot of information on the screen at once, and it is recommended that it be used on devices with a minimum of 1200x800 pixel resolution, landscape or portrait mode.

This app is the free version of the software and the total number of sample intervals (data points) which can be displayed at one time is limited to 100.

该QC SPC图表软件是一个互动的SPC图表（6-Sigma）的应用程序，旨在谁想要在他们的移动设备上查看行业标准统计质量控制图的质量控制专业人员（和学生）。一般用户能够监视在制造，处理，和服务行业临界质量的因素，并且在许多支持的图表类型中的一种显示结果。图表类型包括：可变控制图（X条-R，X条-Σ，独立型，和中值范围），和属性控制图用于监测缺陷（对，NP-，C-，U，和DPMO图表） 。该软件将使用历史数据所支持的可变控制图表自动计算SPC控制限制和属性控制图表类型。警报可以为标准3个西格马控制限制可以产生，或WECO（西电）的规则。它也将计算过程能力比率（CP，CPK）和工艺性能指标（PP，PPK）。一组的规格限制，也可以添加到图表中。

该SPC图表被显示为一个或两个同步图表，滚动条的控制下。滚动条可以通过一个集成的变焦控制，其允许图表与自定义时间帧的显示所替代。图表y轴的自动缩放密切留意一切。一个集成表出现在图中，显示有关下视图的过程信息的上方，并且每个采样间隔在图表中绘出。该表显示时间，各个样本值，样本统计，过程指标，报警状态，并为采样间隔输入的任何注释。

用户可以自定义使用内置的设置形式的SPC图表和控制极限。两个自动计算并手动设置控制限制被支撑。从程序中，用户可以手动输入和编辑的样本数据。用户还可以从CSV（逗号分隔值）文件导入样本数据。整个图表的设置和数据，可以让他们使用该应用程序的下一次都很方便保存在主机设备上。你甚至可以设置当前的设置是自动加载下一次应用程序启动。

软件显示大量的信息在屏幕上一次，并建议将其在设备上以最小的1200x800像素分辨率，横向或纵向模式中使用。

这个程序是该软件的免费版本并且可以在一个时间显示被限制为100个采样间隔（数据点）的总数。
